Question

a train traveled 1/5 of the distance between two cities in 3/4 of an hour ,at this rate what fraction of the distance between two cities can the train travel in one hour

Answer 1

sorry, put the wrong answer and cant delete

Answer 2

4/15 distance

Explanation:

We can use ratio's to solve this, putting distance over time

1/5 distance x distance

---------------- = ----------------------

3/4 hour 1 hour

Using cross products

1/5 * 1 = 3/4 x

1/5 = 3/4 x

Multiply by 4/3 to isolate x

1/5 * 4/3 = 4/3 * 3/4x

4/15 = x

The train can travel 4/15 of the distance in 1 hour
