Question

a tire on a car rotates at 500rpm when the car is traveling at 50 km/h what is the circumference of the tire in meters

Answer 1

50 km/h = 50,000m / hr

= 50,000 / 60 = 833.333 m / minute

The tire rotates 500 times for this period

So the circumference of the tire = 833.333 / 500 m

= 1.67 m to the nearest hundredth

=
