per we starts west from A at 40 mi. per hr.; at 12:10 P.M., another car atarts east from Bul 19. One city, A, is 30 mi. north and 55 mi. east of another city, B. At noon, a car 60 mi, per hr. Find, in two ways, when the cars will be nearest together. Ana. 12:39 20. For the conditions of Ex. 19, draw the appropriate figures for times belen 12:39 P.M. and after that time. Show that in terms of time after noon, the formuly for distance between the two cars (one formula associated with each figure) an equivalent. 10
