Question

A Car Tavels 125km fromschool to home for 2hours.find the speed of the car in km/h and m/s?​

Answer 1

Step-by-step explanation:

Given parameters:

Distance = 125km

Time taken = 2hrs

Unknown:

Speed of the car in km/hr and m/s = ?

Solution:

Speed is the distance divided by the time taken;

Speed =
`(distance)/(time)`

So;

Speed =
`(125)/(2)` = 62.5km/hr

Now in m/s;

1000m = 1km

3600s = 1hr

So;

62.5 x km x
`(1)/(hr)` x
`(1000m)/(1km)` x
`(1hr)/(3600s)` = 17.36m/s
