Question

A man takes 40 secound to complete a sqare of side 10meter what is his distance and displacement an 2minute and 20 second.

Answer 1

Explanation:

since a man takes 40 sec to complete 40m

therefore he takes 10 sec to complete 10 m

and 1 sec to complete 1 m

so distance covered in 2 min 20 sec (140sec) = 140m

and displacement = 10√2m ( since he reaches at the diagonal from the starting point)
