Question

Two trucks leave a warehouse at the same time. One travels due north at an average speed of 48

miles per hour, and the other travels due south at an average speed of 46
miles per hour. After how many hours will the two trucks be 470
miles apart?

Answer 1

The answer is 5hrs

Explanation:

take x to be the no. of hours

48x+46x=470km

94x=470km

now divide 94 from 470

hence, x=5hrs

Answer 2

When two objects are moving in opposite directions, their relative speed is the sum of their speeds. In this scenario, the trucks will be 728 miles apart after 6.5 hours of travel.
