Question

A car is driving at the speed of 58 kilometers per hour. how much time will it take to drive for distance of 32 miles ?

Answer 1

well, we know that there are 1.609 kilometers in 1 mile, so 58 kilometers will be 58 ÷ 1.609 ≈ 36.05 miles.

we know the car is doing 36.05 miles in 1 hour, how long will it be for 32 miles?

`\bf \begin{array}{ccll} miles&hours\\ \cline{1-2} 36.05&1\\ 32&x \end{array}\implies \cfrac{36.05}{32}=\cfrac{1}{x}\implies 36.05x=32 \\\\\\ x=\cfrac{32}{36.05}\implies x\approx 0.8877\qquad \leftarrow \textit{53 minutes and about 16 seconds}`
