speed of farmer=10m/40s.Tell me the his magnitude of displacement at the end of 2minutes20sec.

In 40 seconds the farmer travels 10m

So, in 2min 20 sec i.e. after 140 sec, he will travel ( 10 x 140) /40 = 35m.

if farmer is travelling in a straight line then displacement  at the end of 2minutes20sec is also 35m.
