Question

A road crew Musri pave a road that is 7/8 miles long they can repave 1/56 miles each hour how long will it take the crew to repave the road

Answer 1

Given data :

$1\text{ hour = }\frac{1}{56}miles$

distance required to cover =

$\frac{7}{8}$

thus, the time taken is,

$\begin{gathered} =\frac{\frac{7}{8}}{\frac{1}{56}} \\ =\frac{7}{8}\times56 \\ =\frac{7}{1}\times7 \\ =7\times7 \\ =49 \end{gathered}$

thus the time taken is 49 hours.
