1. An athlete completes one round of a circular track of diameter200 m

1.	1. An athlete completes one round of a circular track of diameter200 m in 40 s. What will be the distance covered and thedisplacement at the end of 2 minutes 20 s?2. Joseph jogs from one end A to the other end B of a straight300 m road in 2 minutes 30 seconds and then turns aroundand jogs 100 m back to point C in another 1 minute. What areJoseph's average speeds and velocities in jogging (a) from A to B and (b) from A to C?3. Abdul, while driving to school, computes the average speed for his trip to be 20 km h-!. On his return trip along the sameroute, there is less traffic and the average speed is 30 km h-1. What is the average speed for Abdul's trip?4. A motorboat starting from rest on a lake accelerates in a straight line at a constant rate of 3.0 m s2 for 8.0 s. How far does theboat travel during this time?
