Suppose a car driven by Emma G. passes a crosswalk while driving at a constant speed of 10 meters per
second and continues driving at this constant speed. Let t represent the number of seconds since the car
passed the crosswalk and let d represent the car's distance from the crosswalk (in meters).
a. Suppose the value of t changes from t = 2 to t = 5.7
i. How much time passes as the value of t changes from t = 2 to t = 5.7?
Δt :
seconds Preview
ii. How much did the car's distance (in meters) from the crosswalk change over this intervtl of
time?
Ad =
meters Preview
iii. Over this interval of time, the change in the car's distance from the crosswalk in meters (Ad) is
how many times as large as the change in the number of seconds since the car passed the
crosswalk (At)?
Ad
At
Preview
b. Over any interval of time, the car's change in distance from the crosswalk (in meters) is
times as large as the change in the number of seconds since the car passed the
crosswalk.
