If you are traveling 65 miles per hour, how many feet will you be traveling in one second? how do you solve this using conversion rates?

There are 5280 foot in a mile. 
For each mile, 5280 feet is therefore gained. So, we multiple 65 by 5280 to convert 65 miles into terms of feet. 
65 * 5280 = 343200
However, this answer of 343200 feet is still in terms of hour. Meaning 65 miles per hour is the same rate as 343200 feet per hour. However the question asks for distance travelled in feet PER SECOND. 
There is 3600 seconds in 1 hour (since 60sec=1min & 60min =1hr : 60*60=3600)
343200 feet/hr is divided by 3600 to convert it into term of feet/sec.
343200/3600 = 95 (1/3)
The answer is that a distance of 95 and a third feet is travelled in 1 second.
