Question

Neha swims in a hundred metre long policy covers 200 metre in 1 minute and 40 seconds by swimming from one end to the other and back along the same straight path find the average speed and average velocity of Neha​

Answer 1

Answer:

Explanation:

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 displacement       =     0 m       =   0 m/s

                                total time taken                   100 s
