You can put this solution on YOUR website! Jesse is traveling at a speed of 105mi/h.
What is his speed in feet per second?
----
Change the miles to feet
Change the hours to seconds.
-----------------------------
(105 mi/1 hr)(1 hr/3600 seconds)(5280 ft/1 mi)
---
= (105*1*5280)/(1*3600*1)(ft/sec)
---
= 154 ft/sec

You can put this solution on YOUR website! 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
