a vehicle covers a distance of 500 km in 4 hours from station A to Station B calculate the speed in km h-1 and ms-1
Answers
Answer:
Distance: 500km
Time: 2Hrs
Step-by-step explanation:
Distance: 500km
Time: 2Hrs
And what’s asked?
Speed: (?)
So as per the formula,
Speed = Distance / Time
putting the given values,
Speed = 500 km/ 2 hrs
Speed = 250 Km/hr
This is the required answer.
And what’s more? We always denote any quantity (Speed, here) in terms of its SI units. In this case, the SI unit of speed is meter per second (m/s). So we need to convert 250 Km/hr into m/s.
For the same, we should know the conversion:
1 Km = 1000 m
1 hour = 60 minutes = 60 x 60 Seconds [we know that 1 minute equals 60 seconds] = 3600 seconds.
Now reaching the final step, what was our answer in km/hr?
250 Km/hr
So putting the value of Km and Hr in it, we get
= 250 x 1000 m / 3600 s
= 69.44 m/s
Answer:
69.44 is correct answer
