The distance to the grazing land is 8100m
The formula for calculating the distance traveled is expressed as:
Given
Speed = 5m/s + 4m/s
Speed = 9m/s
Time = 15 minutes
Substitute the given parameters into the formula
Distance = 9m/s * 15 mins
Distanc = 9 * 15 * 60
Distance = 8100m
Hence the distance to the grazing land is 8100m
