Marlene rides her bike at a rate of 16 miles per hour. The time in hours that she rides is represented by the variable t, and the distance she rides is represented by the variable d. This relationship is modeled with distance d as a function of time t. Which statements are true of the scenario? Select two answers..
Answer
A
The independent variable, the input, is the variable d, representing distance.
B
The distance traveled depends on the amount of time Marlene rides her bike.
C
The initial value of the scenario is 16 miles per hour.
D
The equation t = d + 16 represents the scenario.
E
The function f(t) = 16t represents the scenario.
Explanation
Distance depends on how long Marlene rides, so time t is the input and distance d is the output. At 16 miles per hour, she travels 16t miles in t hours, so the function f(t) = 16t represents the scenario. The initial distance is 0 miles, not 16 miles per hour.
