Correct Answer - Option 3 : 33 sec
Given:
In a 200 metres race A beats B by 35 m or 7 seconds.
Formula used:
Time = Distance/speed
Calculation:
According to the question,
B runs 35 m in 7 second
Speed of B = Distance/time
⇒ 35/7
⇒ 5 m/sec
B covers 200 m in = 200/5
⇒ 40 second
A's time over the course = (40 – 7) second
⇒ 33 second.
∴ A's time over the course is 33 second.
