A boy completes one round of a circular track of diameter 200 m in 30 s. What will be the displacement at the end of 3 minutes and 45 seconds?

Explanation

Total time is 225 seconds (3 \times 60 + 45). Number of rounds = 225 / 30 = 7.5 rounds. After 7.5 rounds, the boy is exactly at the opposite end of the circular track, making the displacement equal to the diameter, which is 200 m.
