Races and Games Practice Test 2 with solutions

Question : 5 of 13

Marks: +1, -0

In a race of 300 metres A beats B by 15 metres or 5 seconds. How much time A does take to complete the race?

Solution:

From the question it is clear that speed of B =

{15}/5

= 3 m/s
The time taken by B to cover 300 m =

{300}/3

= 100 sec.
Hence, time taken by A to complete the race = 100 – 5 = 95 sec.
