Answer:
A takes m second more than B to acquire same speed.
hence we have, v = f×(m+t) = f ' × t ................(1)
from eqn.(1), we get, 
...................(2)
...................(2)A moves n units more than B to acquire same speed
hence we have, 
...............(3)
...............(3)from eqn.(2), we can write, 
.................(4)
.................(4)substitute for (t+m) from eqn.(4) in eqn.(3), we get,
if we substitute t from eqn.(2) in eqn.(5), we have,
