Question

vishnu swims in a 90 m long pool . he covers in one min by swimming one end to another and back along the same straight path , find the average speed and average velocity of vishnu​

Answer 1

Answer:

average velocity= 0m/s

average speed= 3m/s

Explanation:

average speed= total distance/total time taken

                        =180m/60s

                        =3m/s

average velocity {for uniform motion} = total displacement/total time taken

                                                                = 0m/1s

                                                                = 0m/s

hope it helps :)
