Tortise - hare race

  1. Jul 22, 2013 #1
    1. The problem statement, all variables and given/known data

    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 ?

    2. Relevant equations
    D =v/t , 20minute = 120 sec .

    3. 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 ?
