Question

A train goes at a constant speed. If it covers 150 miles in 2 1/2 hours What distance would it cover in 3 hours?

Answer 1

It would cover 180 miles in 3 hours

Explanation:

Distance traveled =150 miles

Time taken to travel 150 miles =
`2(1)/(2) hours`

=
`(5)/(2) hours`

`Speed =(Distance)/(Time)`

`Speed =(150)/((5)/(2))`

`Speed =60`

So, Speed of train = 60 miles per hour

Now we are supposed to find distance covered in 3 hours

Time = 3 hours

Speed of train = 60 miles per hour

`Distance = Speed *Time`

`Distance = 60 * 3`

`Distance =180`

Hence it would cover 180 miles in 3 hours

Answer 2

Hi there!

In order to find your answer, you'll need to use the cross product method :

150 miles → 2 1/2 hours = 150 minutes

x miles → 3 hours = 180 minutes

(150 × 180) ÷ 150 = x miles

27,000 ÷ 150 = x miles

180 = x miles

Your answer is: A train would cover 180 miles in 3 hours.

There you go! I really hope this helped, if there's anything just let me know! :)
