Question

P runs 1 km in 3 minutes and q in 4 minutes 10 secs. How many metres start can p give q in 1 kilometre race, so that the race may end in a dead heat?

Answer 1

the speed of P = 1000/180 m/s

Q = 1000/250 m/s

Distance traveled by Q in the time P end the race is 180*1000/250= 720.

So P should give a start of 1000-720 = 280 m
