You can put this solution on YOUR website! if an arrow travels at 156 feet per second what speed is that in miles per hour?
..
5280 feet = 1mile
so 156 feet = 156/5280 mile..
..
3600 seconds = 1 hour
1 second = 1/3600 of an hour.
..
156 ft/sec = 156/5280 / 1/3600
= (156/5280) *3600
=106.66 mph.
.....
To solve such problems you can multiply feet/sec by 0.6818 to get miles/hour
