A runs 5/3 times as fast as B. If A gives B a start of 80 m, how far must the winning post be so that A and B might reach it at the same time?
Choose the correct choice from the following answers
A) 200 m  B) 300 m  C) 270 m  D) 160 m  E) 360 m
Ratio of the speeds of A and B =	5	: 1 = 5 : 3.   3   Thus, in race of 5 m, A gains 2 m over B.   2 m are gained by A in a race of 5 m.   80 m will be gained by A in race of	5	x 80	m	= 200 m.   2   Winning post is 200 m away from the starting point.   200 mNSWER:200 m
