A can run 1000m in 294sec
B can run 1000m in 300sec
i.e. B can run 10m in 3sec
and A beat B by 6sec
therefore A can give head start of 6sec i.e 20m.

manikanta  (8 years ago)

in this race, A will win by (5 min - 4 min 54 sec) = (300 sec - 294 sec) = 6 sec

B covers 1000 m in 5 min

=> B covers 1000 m in 300 sec

=> B covers 1000300=103m in 1 sec=> B covers 103×6=20 m in 6 sec

i.e., A can give B a start of 20 metre so that the race will end in a dead heat.
