Can you answer this 6 grade math problem? I am a parent and have no idea where to start. Thx?

Cunning Coyote is in a race with Joe Jackrabbit. They both take the same size steps, but the coyote takes 14 steps in the time it takes the rabbit to take 9 steps. Cunning Coyote decided to let Joe get 60 steps ahead before he started to run. How may steps will each runner take (from the time the coyote started running) before the coyote catches up to the rabbit?Can you answer this 6 grade math problem?

I think it is 540
The coyote gains 5 steps on the rabbit for each of unit of time in the race. Since he needs to gain 60 steps, it will take 12 units of time (60 / 5 = 12) to catch up. In 12 units of time, the coyote will take 168 (12 x 14) steps; the rabbit will take 108 (12 x 9) steps.
