Suppose a car driven by Emma G. passes a crosswalk while driving at a constant speed of 5 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). How much did the car's distance (in meters) from the crosswalk change over this interval of time? Δd= meters   Over this interval of time, the change in the car's distance from the crosswalk in meters (Δd) is how many times as large as the change in the number of seconds since the car passed the crosswalk (Δt)?

Question

Suppose a car driven by Emma G. passes a crosswalk while driving at a constant speed of 5 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).

  1. How much did the car's distance (in meters) from the crosswalk change over this interval of time?

    Δd= meters  

  2. Over this interval of time, the change in the car's distance from the crosswalk in meters (Δd) is how many times as large as the change in the number of seconds since the car passed the crosswalk (Δt)?
