2. For the situations described below, define the independent and the dependent variables, and an equation that represents the story
(a) A Car rental agency insures a car for a deposit of $25 and a fee of $4 per hour of rental tim
(1) Zoo animals receive a daily serving of 2 cups of grains and 1 cup of other foods based on

Emily's speed is the greatest, therefor she is the fastest at a speed of 1.78 m/s

Step-by-step explanation:

To determine who swam the fastest we need to calculate the speed for each swimmer;

Speed=Distance/time

Deborah covered a distance of 50 meters in 40.8 seconds,

Deborah's speed=(Deborah's distance/Time)=(50/40.8)=1.23 meters per second

Robert covered a distance of 100 meters in 60.2 seconds,

Robert's speed=(Robert's distance/Time)=(100/60.2)=1.66 meters per second

Emily covered a distance of 200 meters in 112.4 seconds,

Emily's speed=(Emily's distance/Time)=(200/112.4)=1.78 meters per second

From the speeds for each we can conclude that;

Emily's speed(1.78 m/s)>Robert's speed(1.66 m/s)>Deborah's speed(1.23 m/s)

Emily's speed is the greatest, therefor she is the fastest at a speed of 1.78 m/s
