a tortoise can run with a speed of 0.10 m/s and a hare can run 20 times as fast. in a race, they both start at the same time, but the hare stops to rest for 2minutes. The tortoise wins by a shell (20cm). (a) how long does the race take? (b) what is the length of the race?.

answer:

(a)  d=2t+0.2.

d=0.1(t+120).

2t+0.2=0.1(t+120)

t=6.21 s.

(b)  d=2(6.21)+0.2=12.62 m.
