Billy is walking from the front door of his house to his bus stop, which is 940 feet away from his front door. As Billy walks out his front door he walks in a straight path toward his bus stop at a constant rate of 7.5 feet per second
d) What do each of the following represent: f(0) and f(60.25)?
e) Use function notation to represent the following:
i) Billy's distance from the bus stop after he has walked 23.6 seconds
ii) The change in Billy's distance from the bus stop as the number of seconds since Billy left his front door increases from 25 seconds to 48 seconds
f) If t represents the number of seconds since Billy left his front door, solve f(t)=150 for t and say what your answer represents.
