When p completes one round, Q is still 700 behind.
Meaning when P completes 3 rounds, q completes 2 rounds :
When S completes one round q is 300 m ahead of him.
Meaning when s completes 7 rounds q completes 8 rounds.
So when Q completes 8 rounds, S completes 7 rounds and S completes 12 rounds, the three meet together.
The distance covered by q is thus :
8 × 2100 = 16800m
Meaning when P completes 3 rounds, q completes 2 rounds :
When S completes one round q is 300 m ahead of him.
Meaning when s completes 7 rounds q completes 8 rounds.
So when Q completes 8 rounds, S completes 7 rounds and S completes 12 rounds, the three meet together.
The distance covered by q is thus :
8 × 2100 = 16800m
