4. A rat named Littleguy runs in a treadmill (a wire wheel) with a diameter d =8.00 inches. In 5.00 minutes, Littleguy makes the treadmill rotate 2.80 x 10² times. If the rat were running along the ground, how far would he have run? What was his average velocity?

• physics -

the circumference of the wheel is pi*d

revs * in/rev = in

2.8*10^2 * 8pi = 7037 in.

divide by the time to get the speed
