The answer would be 44 feet per second.
Let’s start off with what we do know. 1 mile is equal to 5280 feet. Since the car is traveling at a rate of 30 miles, we can just do 5280 times 30.
5280(30) feet = 158400 feet
The car is traveling at a pace of 158400 feet an hour. Next we’ll have to convert 158400 feet an hour into seconds. There are 3600 seconds in an hour so we can just divide our previous number by 3600.
158400ft/3600 = 44 feet
Good Luck!
