Suppose a person wants to travel D miles at a constant speed of (60 + x) mi/hr, where x could be positive or negative. The time in minutes required to travel D miles is T(x) = 60D(60 + + x) -1. X a. Given the linear approximation to T at the point x = 0 is T(x) L(x) = D 1 60 approximate the amount of time it takes to drive 83 miles at 57 mi/hr. b. What is the exact time required? ... a. The approximate time is min. (Round to the nearest whole number as needed.)
