Question 293132
5280 feet in mile
60 minutes in an hour
60 seconds in a minutes
3600 seconds in an hour
if he were going 1 mile an hour he would go 1 mile in 3600 second.
since one mile is 5280 ft he goes 5280 feet in 3600 seconds
but he goes 105 miles in an hour
so he goes 105*5280 feet in 3600 seconds
so he goes 105*5280/3600 feet in one second
 154 ft  per second
