If in a race of 130m, A covers the distance in 20 seconds and B in 25 seconds, then A beats B by:	Pick
A) 20 m B) 26 m C) 11 m D) 10 m E) 15 m

Rationale: "explanation : the difference in the timing of a and b is 5 seconds . hence , a beats b by 5 seconds . the distance covered by b in 5 seconds = ( 130 * 5 ) / 25 = 26 m hence , a beats b by 26 m . answer b"
Answer: B
