A speedy tortoise can run at 0.14m/s, and a hare can run 15 times as fast. In a race, they start at the same time, but the hare stops to rest for 2 min, so the tortoise wins by a shell(20cm). How long does the race take?
the run the same distance.
set the distances equal, and solve for t, which is time in minutes.
