Race: A contest of speed in running, riding, driving, sailing or rowing is called a
race.
Dead-heat race: If all the persons contesting a race reach the goal at the same
time, then it is called a dead-heat race.

Ex:

A can run a km in 3 min and 54 sec and B can run the same distance in 4 min
and 20 sec. By what distance can A beat B?

A beats B by 26 sec.

Distance covered by B is 260 sec = 1000 mtrs
Distance covered by B is 26 sec = (1000/260)*26
                                                  = 100 mtrs.
Thus, A beats B by 100 mtrs.
