How many turns must a wheel of a diameter of 0.5 make to travel 100m?

To calculate the number of wheel rotations needed to travel a certain distance, we must first find the circumference of the wheel using the formula C = πd, where d is the diameter of the wheel. Given that the diameter is 0.5 meters, the circumference is C = π(0.5) = 1.57 meters. To travel 100 meters, the wheel would need to make 100 / 1.57 = approximately 63.69 rotations. Therefore, the wheel would need to make approximately 64 rotations to travel 100 meters.
