I would solve the first problem this way
1st set of info
Person distance
A 100
B 75
2nd set of info
Person distance
B 100
C 96
We need to find how much distance is covered by C w.r.t A . i.e. when A covers 100 m. In other words when B covers 75m.
Hence the ratio would be
B C
100 96
75 x
so x = 75 * 96/100 = 72. Or you can say this is what C covers when A covered 100 m.
So difference between A and C is 28m i.e. A beats C by 28m
