Question

the car covers500 km in 10 houry.find the speed of the car​

Answer 1

Step-by-step explanation:

So what’s given?

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 2

Answer:

50 let the time taken be T

100/T=10

hence 500=10T

hence T=500/10=50

time taken is 50 hrs
