Two cars are starting from positions that are 20 miles apart. They are both headed for the same intersection, as depicted in the diagram below. Car A is traveling at 30 mph, and Car B is traveling at 45 mph. Which car will reach the intersection first?

A. Use the law of cosines to determine how far Car B has to travel to reach the intersection.

B. Use distance=rate*time to determine the time necessary for Car A to reach the intersection. Round your answer to the nearest hundredth of an hour.

C. Use distance=rate*time to determine the time necessary for Car B to reach the intersection.
