Question

A car travels 500 kms in 4 hours what is it's speed in meter per second​

Answer 1

Answer:

Step-by-step explanation:

First of all, you gotta convert 500km to meters as it is SI unit of speed.

Therefore,

500*1000=500000m

Similarly, convert 2 hours to seconds as it is the SI unit of time.

2*60*60=7200s

We know the formula of speed which is,

s=d/t where d is the distance covered by the object in meters (m) and t is the time taken in seconds (s)

So,

500000/7200

69.44 m/s

Therefore, the car is travelling a 69.44 m/s.

Answer 2

Step-by-step explanation:

speed- distance/time

speed- 500/4

- 125km/hr

km/hr×18/5 - m/s

125×18/5- 450m/s
