The circumference is about 3 1/7 times the length of its diameter. how far will a wheel with a diameter of 5/6 m roll back, having made: 1) one turn 2) two turns 3) three and a half turns?

Let’s write down the wheel data: diameter d = 5/6 m, the length of the wheel rim according to the condition is (3 1/7) * d = 10/7 * 5/6 m = 50/42 = 25/21 m.

1) The length of the wheel rim is equal to the length of the distance that the wheel travels in 1 revolution, or 25/21 m = 1 4/21 m = 119 cm.

2) In 2 revolutions, the wheel will roll back a distance equal to: 25/21 * 2 m = 50/21 m = 2 8/21 m = 238 cm.

3) In 3.5 revolutions, the wheel will roll back a distance equal to: 25/21 * 3.5 m = 87.5 / 21 m = 4.16 m = 416 cm.
