Question

A farmer is moving on the boundary of the equilateral triangle field abc of side 100 m with fixed speed .farmer takes 15 min to complete the one round of the field . the displacement of the farmer after 10 min .

Answer 1

Answer:

100 m

Explanation:

Suppose the farmer start from point A, after completion of one round he will reach A point again. In completion of one round he take 15min and there are 3 sides of triangle and this is a equilateral triangle , so he will take 5 min to cover one side of triangle .

15/3 = 5

So, in 10 min he will cover two sides and reach point B.

Displacement between A and B is the exact distance between them i.e. 100m .

So in 10min he’ll displace 100m
