A boy walks from his classroom to the bookshop along a straight corridor towards North. He covers a distance of 40 m in 50 seconds to reach the bookshop. After buying a book, he travels the same distance in the same time to reach back in the classroom. Find (a) average speed, and (b) average velocity, of the boy

Answer :

(a) Total distance covered in going to the bookshop and coming back to the classroom = 40 + 40 = 80m

Total time taken= 50 + 50 = 100sec

80/100 m/s = 0.8 m/s

0/100 m/s = 0 m/s
