Question

How can I convert 345 ft/min to ft/h ?

Answer 1

60min=1hr
1min=1/60hr

so

$\frac{345ft}{1min}=\frac{345ft}{\frac{1}{60}hr}=$
$\frac{(345ft)(60)}{1hr}=\frac{20700ft}{1hr}$

Answer 2

Since there are 60 minutes in an hour, just take 345 and multiply by 60 which will give you 20,700. So your final answer would be 20,700 ft/hr
