Read Solution (Total 2)

In a 400 m race - Ratio of distances
A:B:C
400:380:361
So, when B runs 380 m -> C runs 361 m
when B runs 400 -> c runs 361*400/380=380m
The start B can give C= 400-380=20 m

before A has started the race, B has walked 20m & C has walked 39m. => before B has startes, C has walked 39-20=19m. if this is not the answer, then i think, data is inadequate. without knowing their speeds, its impossible to find out.
