Calculating the Length of the Tortoise-Hare Race

[Anthonyphy2013]

Homework Statement

A speedy tortoise can run with a velocity of 01m/s and a hare can run 2.0m/s . In a race , the hare gives the tortoise a 2- minute head start. The tortoise wins the race by a shell ( 0.2m ) . What was the length of the race ?

Homework Equations

D =v/t , 20minute = 120 sec .

The Attempt at a Solution

D = distance , t = time for tortoise to run , t1 for the time of hare to run
for hare , D-0.2=2(t-120)
and for tortoise , D= 0.1 t
is that corrected ?
