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
(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

Question

(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
