Bicycle walking mileage must be, the number of revolutions of the wheel and the diameter of the wheel inversely proportional. ... ______. (judge right or not)
The length of the number of revolutions = distance, that is, diameter × π × speed = distance (certain), that is, the diameter of the number of revolutions = distance ÷ π, a certain distance, distance ÷ π also must, diameter and speed of the product must be, so Inversely proportional. So the answer is: correct.
