The histogram shows the number of chicks born to non-migratory Canada geese in a city park, with the horizontal axis representin
g the number of hatchlings and the vertical axis representing the number of nests. For example, there were 15 nests with 0-3 hatchlings.
In order to monitor the geese population, the state wildlife service annually samples the number of hatchlings from 30 nests using a simulation. Which number of hatchlings would be a reasonable outcome for the simulation?

First, determine the distance of the motorcycle and the car from the start point. The distance could be determined using
d stands for distance, v stands for speed, t stands for time
The car
d = 48 × t
d = 48t
The motorcycle
d = 20 × t
d = 20t
At the end of t hours, the car is 48t miles (east) from the start point and the motorcycle is 20t miles (north) from the start point.
Second, determine the distance between 48t miles at east and 20t miles at north using pythagoras
distance =
distance =
distance =
distance = 52t
The expression for their distance apart at the end of t hours is 52t
