Question 1:
In a race of 300 metres A rates B by 15 metres or 5 seconds, Hoe much time A take to complete the race?
A. 105 sec.
B.100 sec.
C.95 sec.
FeedbackFrom 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.
D.90 sec.
