The wheels of a car have a 24-in diameter. When the car is being driven so that the wheels make 10 revolutions per second, how far will the car travel in one minute?
I need an answer and how you got to it..

how do you know that 10rps = 600 rpm? I don't understand?

10 revolutions in one second
600 revolutions in 1 minute.
you put 10 revolutions over one second, and
then you multiply it by 60 seconds over one minute
so that the seconds cancel out, and you are left
600 revolutions over 1 minute.

10rps=600rpm
24"=2' diameter
c=2*pi ft
600revs the car goes 600*2*pi ft=1200*pi=3770ft=.714mi

one revolution = the circumference of the tire
= pi*d = 3.14 *24 = 75.26 inches = 6.28 ft
in one sec = 10 rev = 62.8 ft
in one minute = 60 sec = 60 * 62.8 = 3768 ft or 45,216 inches

10*60 is 600 revolutions... c=2*pi ft
600revs the car goes 600*2*pi ft=1200*pi=3770ft=.714mi
PS please award best answer
