Question

a bus travels 36 miles in 45 minutes what is the number of miles the bus travels in 60 minutes at this rate

Answer 1

`\bf \begin{array}{ccll}miles&minutes\\\cline{1-2}36&45\\x&60\end{array}\implies \cfrac{36}{x}=\cfrac{45}{60}\implies \cfrac{36}{x}=\cfrac{3}{4}\implies \cfrac{36\cdot 4}{3}=x\implies 48=x`
