Question

A train goes at a constant speed. If it covers 150 miles in 2.5 hours,How long would it take for that train to cover 100 miles?

Answer 1

1.666666666666667

Explanation:

First
`(150)/(2.5) =(100)/(x)`

`x=(360 * 2.5)/(150)`

`x=(960)/(360)`

`x=1.666666666666667`

Answer 2

The sped of the train is constant.

Time taken to cover a distance of 150 miles = 2.5 hours

Time taken to cover a distance of 1 mile =
`(2.5)/(150)`

So, time taken to cover a distance of 100 miles is =

`(2.5)/(150)*100` = 1.66

Hence, the train will take 1.66 hours to cover a distance of 100 miles.
