Question

how long will a boy take to run around a square field of side 35 M if he runs at the rate of 9 km per hour​

Answer 1

Answer:

56 second or approximately 1 minute

Step-by-step explanation:

Perimeter of the square Is four times of its side.

i.e., 4 * 35 = 140 meters

Boy covered a distance of 9000 meters (9 km = 9*1000= 9000 meters) in one hour. That's 60 minutes.

For covering a distance of 9000 meters he took 60 minutes.

Hence for 140 meters he will take time = 60 / 9000 * 140 = 14 / 15 minutes = 14 * 60 /15 = 56 seconds.

So he will take 56 seconds to complete his task.
