Two planes leave an airport at the same time, traveling on runways that have an angle of 42° between them. If one plane travels at an average speed of 220 mph and the other plane travels at an average speed of 280 mph, how far apart are the two planes after 4.5 hours? (Round to one decimal place.)

First, find the relationship between the number of minutes, x, she works and the number of sundaes,s, she makesshe makes s = [1sundae / 2 minutes]* x = x/2now find the relation of the earnings, e, with the number of sundaes she works    e =  $1.20* s = 1.2s.and finally, relate e with the number of minutes she works,  x: e = 1.2 [ x/2]e = 0.6x
