What will be the time to close a gap to catch a breakaway?
how much time is required to close a gap of 100 metres, in a cycling race, for different differences in speed of leading and chasing group


For a speed difference of 1 metre per second, the time is 100 seconds.

For a speed difference of 2 metres per second, the time is 50 seconds.

For a speed difference of 0.5 metres per second, the time is 200 seconds.

Generally, for a speed difference of "x" metres per second, the time is "100 divided by x" seconds.


  i need a tool to do the math on the fly. so that if one knows what speed the chasing group, one should be able to decide the speed to keep gap constant


To keep the gap constant, the lead group must maintain exactly the same speed as the chasing group.
