Answer» 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.
