Homework #3 Solutions Problem #1. A driver takes 3.0 seconds to react to a complex situation while traveling at a speed of 55 mph. How far does the vehicle travel before the driver initiates a physical response (i.e., putting their foot on the brake)? How does this compare to the standard reaction time of 2.5 seconds? How does it compared to an attentive, younger driver with a reaction time of 1.25 seconds? Brake Reaction Distance dR 1.47Vt 1.47(55)(3)  242.55 ft 1.47(55)(2.5...
