Atortoise can run with a speed of 0.14 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 1.0 minutes. the tortoise wins by a shell (30 cm). (a) how long does the race take? s (b) what is the length of the race?

speed of tortoise is given as v1 = 0.14 m/s

speed of hare is given as v2 = 20*0.14 = 2.8 m/s

now let say the total length of the path is "d"

so the total time taken by the tortoise to cover this

now given that hare took rest for 1 min

so total time of run for hare is (t - 60)s

so the distance that hare covered is given by

now by above two equations

and the time t is given by

so part a)

t = 63 s

part b)

d = 8.82 m

magnified images possible images can be real = projected onto a screen

i think the answer is a and b

i wish you luck
