287. Car and Circle. A car is driving in a circle. The wheels on the outer side of the circle move twice as fast as the wheels on the inner side.

What is the length of the circumference traveled by the outer wheels if the distance between the wheels on both axles is 1.5 m?
287. Since the outer wheels move twice as fast as the inner ones, the length of the circumference they describe is twice the length of the inner circumference. Therefore, the diameter of one circle is twice the diameter of the other. Since the distance between the wheels is 1.5 m, the diameter of the larger circle is 6 m. Multiplying 6 m by 3.1416 (the usual approximate value of the number \(\pi\)), we get 18.85 m - the length of the circumference of the larger circle.
