Distance and Time You are travelling in a car at an average speed of 50~km/hr. Write a linear equation in two variables to find out the distance you have travelled after a certain number of hours. Used for distance travelled and use 'X for hours. Linear equation in two variables in the form ax+by+c=0
Answers
Step-by-step explanation:
The car is travelling at the average speed of 50 km/hr means it is travelling 50 kilometers in 1 hour.
1 hour = 60 minutes
1 hour and 12 minutes = 60 minutes + 12 minutes = 72 minutes
In 60 minutes car travels 50 kilometers
In 1 minute it travels = 50/60 kilometers
In 72 minutes it will travel = 50/60 × 72 kilometers
50/60 × 72
=50/5 × 6
= 10 × 6
= 60 kilometers.
Thus in 1 hour 12 minutes, the car will travel 60 kilometers at the speed of 50 Km/hr
Answer in 1 hour 12 minutes, the car will travel 60 kilometers at the speed of 50 Km/hr
A car travels at an average speed of 50 km/h. What distance will it travel in 30 minutes?
A car is travelling 50 km in 1 hours. How much of a distance will it travel in 12 minutes?
A car is travelling 50 km in one hour. How much distance would it cover in 12 minutes?
A car travelling at the average speed of 50km/h. How much distance would it travel in 12 minutes?
A car is travelling at the speed of 50 km per hour. How much time will it take to cover a distance of 150 km?
The first thing we should know, is about correct SI units . For instance , here time is given in hours and minutes so we should convert minutes to hours. It follows as 1 hours =60 min. so 12min.=12/60 hours = 1/5 hours Now total time= 1/5 +1=6/5 hours . So first thing is clear. Now we have to know formula: average velocity= total distance/total time so putting appropriate value we write as: 50km/hr=total distance/6/5. So total distance= 50×6/5=60 km. So, we get our result. Also, we have to be conscious of system of units such as metres, sec, etc.

Impossible to answer. If the “average speed” in one hour make the car travel 50km, it means the speed could not be constant. So, it could be 90km/h during the first 30 minutes and 10km/h during the second 30 minutes. If this is the case, for example, in the next 12 minutes after the first hour, the car could be traveled 18km at 90km/h, completing 50 + 18 = 68km. The tricky word “average” makes it impossible to answer. Good try, but no cigar.
To use solve this, we can use the formula Distance = Speed * Time. First We need to convert 1 hour and 12 minutes into just hours. We can do this by:
12 / 60 * 100 = 20% of an hour
Therefore the car travels for 1 hour and 20% of an hour or 1.2 hours. We can then find the distance by:
Distance = speed * Time = 50 km/hr * 1.2 hours = 60km.
A car is travelling at an average speed of 60 km per hour. How much distance will it cover in 1 hour 12 minutes?
If a car is traveling at 50 km per hour, how far will this car travel in 30 minutes?
A car is travelling at average speed of 60km per hour. How much distance will it cover in 1hour 12minutes?
A bus is travelling at an average speed of 50 km/h. What distance will it cover in 12 minutes?
A car is traveling at an average speed of 55 km/hr. How much distance would it cover in 12 minutes?
That depends on how fast it travels for the next 1.2 hours. If it slams into a brick wall at 50km/hr and then stays there for the next 72 minutes before the tow truck comes, then 0 miles. If it was falling at the time of this question, then it mostly depends on its starting altitude. But “travelling at an average speed” doesn’t actually mean anything, so I’m not sure what else to say. An average rate has to be over some period of time.

Twelve minutes is 12/60 = 1/5 = 0.2 hours. So the car travelled for 1.2 hours.
The car travelled at an average of 50 km/hr for 1.2 hours, so it travelled 50 km/hr * 1.2 hours = 60 km.
1/5th of 60mins is 12, so we are essentially looking at 50km + 1/5th of 50km
So effectively the equation comes down to:
(50 x 1.2) or (50 + 50/5)
= 50 + 10
= 60km in 72mins
i do not know why quora keeps sending me these sorts of questions….they seem to be somebody’s homework questions, and most anyone with more then primary school education can solve this….
I enjoy getting real questions.. I’m trying not to be stuck up or anything, but I don’t think this is a worthwhile question, certainly taking into account that it might be some kid trying to avoid putting some thought in their homework,….
So in one hour it will travel 50 km and in 12 minutes - 12/60 x 50 = 10 km
so he would travel 60 km
The question has already been answered by Quora folks. But some are curious why it was asked, just a random one, or a homework assignment.
50/60×72=60
=60 km
