Question

If a train travels 5/6 miles in a 5/4 minutes how many miles will it travel in one hour

Answer 1

40 miles
1 hour means 60 min.
(5/6*60)÷5/4=40

Answer 2

$In \frac{5}{4} minutes a train travels \frac{5}{6}miles\\ In 1 minute a train travels (\frac{(5/6)}{(5/4)} = \frac{5}{6} *\frac{4}{5} = \frac{2}{3} miles\\In 60 minutes a train travels \frac{2}{3} *60 = 40 miles\\Note - 1hour = 60 minutes$

So, Answer is 40 miles.
