Question

How many hours will it take to complete a 63-km bike ride if you go 20 km per

hour the whole time?

Answer 1

Answer: 3 for whole numbers, but if you want to be exact, 3 and 3/20 (three and three twentieths)

Explanation:

20 times 3 is 60, and there is 3 left so you would make it a fraction since it won't divide into 20.

Answer 2

Answer: time = 3.15 hrs

Explanation:

distance = 63km

speed = 20km/hr

time = ?

speed = distance / time

therefore :

time = distance / speed

time = 63/20

time = 3.15 hours
