Question

The distance of a train from a station, varies directly with the time, t. If d = 100

miles when t = 2 hours, find d when t = 3.

Answer 1

d=150 when t=3

Explanation:

First you would need to find what d equals when t=1

100 ÷ 2 =50

d=50 when t=1

Then you need to find the total

100 + 50 = 150

d=150 when t=3
