Cory and Melissa are racing electronic cars around a circular track. They begin at the same time going in the same direction. Cory’s car completes a revolution in 40 seconds, while Melissa’s car completes a revolution in 35 seconds. How long will it take them before both cars reach the starting point again simultaneously?
