Question

6. The length of a square field is 35m. What distance will a man walk in going
around it 3 times ?​

Answer 1

Answer:

Side of square field = 35 m

Perimeter of square field = 4 × 35 m = 140 m

Rate at which the boy runs = 9 km/hr

Converting km/hr in m/s

1 km/hr = 5/18 m/s

9km/hr = 9× 5/18 = 2.5 m/s

Now , according to the question

Time taken to run around the square field = Perimeter of square field × rate at which the boy runs

= 140 m ÷ 2.5 m/s

= 56 seconds

Converting seconds into minutes

60 seconds = 1 minute

56 seconds = 56/60 = 0.93 minutes (approx.)

Hence , the time taken by the boy to run around the square field is 56 seconds or 0.93 minutes (approx.) at the rate of 9 km/hr .

Hope you get it !
