Solution 1.4.3 Cheetah at t = 0 Gazelle at t= 0 Cheetah at t= 0.1 Gazelle at t = 0.1 Figure 1: Positions of cheetah and gazelle at t =0ant t =0:1 Wehave 40 miles 1hour  5280 feet 1mile  1hour 3600 sec 0:1 sec = 5:8667 ft 70 miles 1hour  5280 feet 1mile  1hour 3600 sec 0:1 sec = 10:2667 ft The situation at time t =0andt =0:1isshown in Figure 1. The human reaction time is 0.2 s. If the cheetah's is 0.1 s, then the cheetah will turn right where the gazelle turned. 1
