Dr= distance rabbit runs    Tr= Time rabbit runs    Sr = rabbit speed
Dt= distance totoise runs    St = tortoise speed
Dt= St x rabbit rest    +  St x Tr + winning advantage
Dt= (10cm/sec x 120sec) + (10cm/sec x Tr) + 10cm
Dt= 1210 cm +(10cm/sec x Tr)

Dr= rabbit speed x Tr
Dr= 200 cm/sec x Tr
Dr= tortoise head start    + distance when rbbit runs .Also
Dr= St x rabbit rest    +  St x Tr
Dr= (10cm/sec x 120sec) + (10cm/sec x Tr)

Dr = 1200cm + 10cm/sec x Tr =200cm/sec Tr
        1200cm = 190 cm/sec x Tr
       6.316sec = Tr ( the time the rabbit actually runs)
substituting
Dt = 1210cm  + 10 cm/sec x 6.316sec = 1273 cm (distance toroise actually
runs)
Dr = Sr x Tr = 200cm/sec x 6.316sec = 1263 cm  (distance rabbit actually
runs)

1273cm -1263cm = 10cm by which tortoise wins
