Question

A farmer moves along the
boundary of a square field of side
10 m in 40 s. What will be the
magnitude of displacement of the
farmer at the end of 2 minutes 20
seconds from his initial position?​

Length of square field =10m

Time taken to move along square field =40 s

Total time the farmer walked on square field

=2 min 20 sec

=2x60+20

=140 sec
