Answer 2

Calculation of the Number of Flags

To calculate the number of flags needed on a circular track, we need to determine the circumference of the track and divide it by the distance between each flag.

Given: - The track is circular with a circumference of 400 meters. - Flags are placed every 5 meters.

To calculate the number of flags, we divide the circumference of the track by the distance between each flag:

Number of flags = Circumference of track / Distance between flags

Circumference of track = 400 meters

Distance between flags = 5 meters

Number of flags = 400 meters / 5 meters = 80

Therefore, the correct answer is D) 80 flags.
