Question

Neha swims in a 100m long pool. She covers 200m in one minute and forty seconds by swimming from one end to the other and back along the same straight path .find average speed and average velocity of neha

Answer 1

length of pool = 100m

total time taken = 1 min + 40s = 60s + 40s = 100s

total distance covered by Neha = 200m

therefore, the total displacement covered by Neha = 0m
[because she swims from one end of the pool to the other and back along the same straight path, to her original position.]


Now, According to the question-

average speed =    total distance        =     200 m       =   2 m/s
                               total time taken              100 s


average velocity =     total displacemet       =     0 m       =   0 m/s
                                 total time taken                   100 s
