Question

Two Amazon delivery trucks leave a warehouse W at exactly 2:00 pm, driving on 2

different highway routes that are separated by an angle of 140°. Truck A is

traveling at 60 miles per hour, and truck B is traveling at 50 miles per hour. At

2:30 pm, what is the distance, in miles, between trucks A and B?

Answer 1

(2.5-2)*sqrt(50^2+60^2-2*50*60 * cos 140°) = 51.71 miles
