Question

How would you convert 9 km/hour to feet/minute? Oh, and please show the steps you took to get there. Thank you. (This is worth extra points btw)

Answer 1

keeping in mind that

there are 1.609 kms in 1 mile

5280 feet in 1 mile

and 60 minutes in 1 hr.


`\bf \cfrac{9~\underline{km}}{\underline{hr}}\cdot \cfrac{\underline{mile}}{1.609~\underline{km}}\cdot \cfrac{5280~ft}{\underline{mile}}\cdot \cfrac{\underline{hr}}{60~mins}\implies \cfrac{9\cdot 5280~ft}{1.609\cdot 60~mins} \\\\\\ \cfrac{47520~ft}{96.54~mins}\approx 492.2311995(ft)/(min)`
