A tortoise can crawl 8 m in one minute. A rabbit can run at a speed of 40 m in one minute. The two are having a race one day. While the tortoise crawls continually, the rabbit rests for 3 minutes after every 2 minutes' run. How far does the rabbit run when the tortoise crawls 360 m?
answer 720
method The tortoise never stops, so use it as the clock: 360 ÷ 8 = 45 minutes for the whole race. The rabbit's pattern repeats every 2 + 3 = 5 minutes, and in each 5-minute cycle it covers 2 × 40 = 80 m. In 45 minutes there are 45 ÷ 5 = 9 complete cycles, so the rabbit runs 9 × 80 = 720 m.
watch Working out 45 minutes × 40 m = 1800 m and forgetting the rabbit spends 3 of every 5 minutes resting. Find the TIME first, then the repeating cycle.
