You can put this solution on YOUR website! If car A has a 25% faster speed than car B, how much faster will car A reach point A? Just need a simple answer, lots of variables that I don't know what to do with.
----------------
25% faster is 1.25 times as fast, or 5/4 as fast.
That means the time will be 4/5 as long as car B.
The amount of time difference depends on the distance abd the speeds.
-----
If car B takes 5 hours, car A will take 4 hours.
t(A) = time for A, t(B) = time for b
-----
t(A) = 0.8*t(B)
