A train travels 900 miles in 9 hours. How long
will it take the train to travel 1150 miles?

Answer 1

11.5 [h].

Explanation:

1) if the unknown time is 't', then

2) it is possible to make up the equation:

`(900)/(9) =(1150)/(t);`

3) if to solve this equation, then t is:

t=1150*9/900=1150/100=11.5 [hours].
