Children need to stand at an interval of 300 m to direct the runners. How many children are needed? At what positions from the starting point will the children be standing?

Correct Answer

Given:

  • Total distance = 3000 m
  • Interval = 300 m

Calculation: Number of positions = 3000 ÷ 300 = 10

Answer: Children needed: 10 (or 11 including start)

Positions from starting point: 300 m, 600 m, 900 m, 1200 m, 1500 m, 1800 m, 2100 m, 2400 m, 2700 m, 3000 m
