A boy swims in a 90 m long pool. He covers 180 m in one minute by swimming from one end to the other and back along the same straight path. Find the average speed and average velocity of the boy
Step 1: Given data
Average speed and average velocity
Step 2: Find the average speed
Let be the average speed of the body.
Step 3: Find the average velocity
Let be the average velocity of the body.
So, the average speed of the body is and the average velocity of the body is zero.
