A car travels on a highway at an average speed of 65 miles per hour. What was the speed in feet per second?

(Remember- 1 mile=5280 feet)

65mi/hr * 5280ft/mi * 1hr/3600s = 95.33 ft/s

Thank you, thank you, thank you, thank you!!!! I appreciate it very much! I worked on this for no lie, 30 minutes or so and could never get an answer that was one of the choices! Thank you soooooo much!

when converting from one unit to another, just remember that you can always multiply by 1 without changing the truth of the expression. If you keep track of the units, you can always set things up so that you can cancel the unwanted units.

To convert feet to inches, just multiply by 1: 12in/ft !

To find the speed in feet per second, we need to convert miles per hour to feet per second.

First, we convert 65 miles per hour to feet per hour. Since 1 mile is equal to 5280 feet, we can multiply 65 by 5280 to get the distance in feet:

65 miles/hour * 5280 feet/mile = 343,200 feet/hour

Next, we convert feet per hour to feet per second. There are 60 minutes in an hour, and 60 seconds in a minute, so multiply 343,200 by (1/60) and then again by (1/60) to convert hours to seconds:

343,200 feet/hour * (1/60) minute/hour * (1/60) hour/minute = 95.33 feet/second

Therefore, the speed in feet per second is approximately 95.33 feet per second.
