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 = 5.4 i. How much time passes as the value of t changes from t = 2 to t = 5.4? At = seconds Preview ii. How much did the car's distance (in meters) from the crosswalk change over this interval 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 Preview At 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.
