ANS : 10root 2

Answer 2

Answer:

14.142

Explanation:

Total distance 40m in 40 sec.

Total time taken by the farmer = 2 min 20 sec. = 140 seconds.

Total rounds completed= 140 / 40 = 3.5 rounds

That means if the farmer starts from point A of the square field, he reaches point C.

Therefore, displacement is AC.

Assume ABC is a right angled triangle.

Therefore,

AC² = AB² +BC²  

AC² = (10)² + (10)²

AC² =  100 + 100

AC² = 200

AC = √(200)

AC = 14.142
