a. running track has a perimeter of 800*1/4meters if a runner takes five round of it how much distance did he cover?

naturally, 5 times the perimeter.

my ans is 1000m

To find out how much distance the runner covered, we need to calculate the total perimeter of the running track.

Given:
Perimeter of the running track = 800 * 1/4 meters

To find the distance covered by the runner, we need to multiply the perimeter by the number of rounds the runner took.

Number of rounds = 5

Distance covered = Perimeter * Number of rounds

Distance covered = (800 * 1/4) * 5

Distance covered = 800 * 1/4 * 5

Let's simplify this calculation:

Distance covered = 200 * 5

Distance covered = 1000 meters

Therefore, the runner covered a distance of 1000 meters by taking five rounds of the running track.

To find out how much distance the runner covered, we need to multiply the perimeter of the running track by the number of rounds the runner took.

First, let's find the perimeter of the running track. It is given as 800*1/4 meters, which means 800 divided by 4 equals 200 meters. So the perimeter of the running track is 200 meters.

Next, we multiply the perimeter (200 meters) by the number of rounds the runner took (5 rounds).

200 meters * 5 rounds = 1000 meters.

Therefore, the runner covered a distance of 1000 meters.
