Question

Solve question no. 2 ​

Answer 1

Answer:

5 meter

Explanation:

total time in second= 2*60+20=140sec

10 m in 40 sec

than in 140 sec distance traveled = 140/40

=35 m

but displacement = final poin - initial point

and the distance of 30 m in displacement =0

and the total displacement=5 meter

Answer 2

Answer:

Here, Side of the given square field = 10m

so, perimeter of a square = 4*side = 10 m * 4 = 40 m

Farmer takes 40 s to move along the boundary.

Displacement after 2 minutes 20 s = 2 * 60 s + 20 s = 140 seconds

since in 40 s farmer moves 40 m

Therefore, in 1s the distance covered by farmer = 40 / 40 m = 1m

Therefore, in 140s distance covered by farmer = 1 � 140 m = 140 m. Now, number of rotation to cover 140 along the boundary= Total Distance / Perimeter

= 140 m / 40 m = 3.5 round

Thus, after 3.5 round farmer will at point C of the field.
