Question

Area of a square field is 24200 sq m. How long will it take for a person to cross the field diagonally at the rate of 4.4 km/ h

Answer 1

Hello Dear,

◆ Answer -

Time taken = 3 min

◆ Explaination -

In terms of diagonal, area of square is given by -

A = d²/2

d² = 2A

d² = 2 × 24200

d² = 48400

d = √48400

d = 220 m

d = 0.22 km

Time taken to cross diagonally is -

t = s / v

t = 0.22 / 4.4

t = 0.05 h

t = 3 min

Therefore, the person will take 3 min to cross the field diagonally.

Thanks dear...
