one car takes 2 minutes for one round
So it does 1/2 round in 1 minute
.
second car takes 1 1/2 mins for 1 round .. (3/2 minutes)
it does 2/3 round in 1 minute
every minute the second car gains 2/3 -1/2 of the round
=4-3 / 6
=1/6 of the track.
6 minutes iit takes to gain one round of track.
Every 6 minutes the faster car overtakes the slower car.
