You are in a bike race. When you get to the first checkpoint you are 2/5 of the distance to the second checkpoint. When you get

Mamont248 [21]

The first checkpoint = 1check
the second checkpoint = 2check
complete distance = f

1check = 2/5 (2check)
2check = 1/4 (f)
then
1check = 2/5 * 1/4 (f)
1check = 1/10 f
the distance of the first check point is 1/10 of the distance of race
