Question

A girl bikes for 3 hours at a speed of 40 km/hr. What distance did she travel?

Answer 1

The rate tells us that, in every 1 hour, 40km. But she travels for 3 hours, and in each of those three hours she goes 40km. 40km for the first hour, 40km for the second, 40km for the third ... 3 * 40km = 120km.

D=RT

D=(40 km/hr.) (3hrs)

=[40(3)] multiply = d=120 km is the distance she traveled on her bike.

Answer 2

distance = 120km

Step-by-step explanation:

speed = 40km/hr

time = 3 hours

distance = ?

speed = distance/time

distance = speed × time ( making distance the subject)

distance = 40km/hr × 3 hrs

distance = 120km
