Question

starting from 300 ft away, a car drives towards you. it then passes by you at a speed of 48 feet per second. the distance d (in feet) of the car from you after t second is given by equaction d= | 300-48t|. at what time is the car 60 feet from you

Answer 1

To solve for the time when car is 60 feet from you, simply plug in into the equation d = 60 feet:

60 = 300 – 48 t

48 t = 300 – 60

48 t = 240

t = 5 seconds

Therefore the car is 60 feet away after 5 seconds.
