Two trains leave a station at 11:00am. One train travels north at a rate of 75 mph and another travels
east at a rate of 60 mph. Assuming the trains do not stop, about how many minutes will it take for the
trains to be 250 miles apart?

V1 = 75i mi/h.
V2 = 60 mi/h
Tan A = V1/V2=75/60 = 1.2500, A = 51.3o.
d1 = 250*sin51.3 = 195 mi.
V1*T = 195, 75 * T = 195, T = 2.60 h. =
156 min.
V2 = 60 mi/h
Tan A = V1/V2=75/60 = 1.2500, A = 51.3o.
d1 = 250*sin51.3 = 195 mi.
