Question

How many times will a boy have to run around a square plot whose length is 60 metres to covera distance of 6 km.​

Answer 1

Step-by-step explanation:

Perimeter of the square Is four times of its side.

Perimeter of the square Is four times of its side.ie., 4 * 35 = 140 meters

Perimeter of the square Is four times of its side.ie., 4 * 35 = 140 metersBoy covered a distance of 9000 meters (9 km = 9•1000= 9000 meters) in one hour. That's 60 minutes.

Perimeter of the square Is four times of its side.ie., 4 * 35 = 140 metersBoy 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.

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.

Answer 2

Answer:

$perimeter = 4 \times side \\ = 4 \times 60 \\ = 240 \\ total \: distance = 1.2km = 1200m \\ number \: of \: rounds \: = \frac{total \: distance}{perimeter} \\ = \frac{1200}{240} \\ = 5 \: rounds$

hope it helps you ☺️☺️☺️
