Question 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?
Total distance = 3 km = 3000 m
Distance between two children = 300 m
So, the number of children needed = 3000 -r 300 = 10
The children will be standing at, 300 m, 600 m, 900 m, 1200 m, 1500 m, 1800 m, 2100 m, 2400 m, 2700 m and 3000 m.
