estimated a driver takes on average 1.5 sec from seeing obstacle to reacting by applying the brake or swerving. How far will car traveling at 79 mph travel (in ft) before driver reacts to obstacle?

Answer 1

(79 mi/hr)(1 hr/60 min)(1 min /60sec)(5280 ft/1 mi) = 115.8666 ft/sec

(115.8666 ft/sec)(1.5 sec) = 173.8 ft
