Question 4 the day: May 22, 2003

The question for the day is from the topic of Races.
A runs 13/5 times as fast as B. If A gives a start of 240m, how far must the post be so that A and B might reach at the same time.

(1) 390 m (2) 330 m
(3) 600 m (4) 720 m
Correct Answer - (1)

Solution:


A runs 13/5 times fast as B which means A runs 13 metres for every 5 meters of B.

Therefore, A gains 8 metre in a 11m race or if A gives a start of 8m in a 13m race then the race might end in a dead heat.

Therefore, if A gives a start of 240m (8* 30) then the length of the race should be equal to 13*30 = 390m

Or the length of the race after A gives a start of 240 start so that A and B reach at the same time is given by (240*13) /8 = 390m.
