I need help with this please

Question:

A 1,000kg car travels around a circular track at a constant speed. if the radius of the path is 200 m and the car is traveling at 25 m/s, how long does it take the car to make a lap around the track?

Step by step:

Perimeter = 2π r = 2π 200

400 * π = 1256m

1256 ÷ 25= 50. 24 seconds

50.24 = 50.2 seconds

your final answer is 50.2 seconds

I hope this helps!!
