Question

A boy walks at a speed of 4 kmph. How much time does he take to walk a distance of 20 km? Show your work!

Answer 1

5 hours

Explanation:

The relationship for distance, time, and speed is:
`d=st` , where d is the distance, s is the speed, and t is the time.

We are given the boy's speed is 4 kmph, so s = 4. We also know the distance is 20 km, so d = 20.

Then, rearranging the above formula, we have
`t=(d)/(s)` . We plug in the values of d and s into the equation to find t:

`t = (d)/(s) =(20)/(4) =5`

Thus, the answer is 5 hours.

Hope this helps!

Answer 2

20km/4km/h=5h
