In the movie Close Encounters of Third Kind, there was a scene where the star, Richard Dreyfuss, was approaching Devil’s Tower in Wyoming. He could have determined his distance from Devil’s Tower by first stopping at point P, and taken a measurement of the angle from his location to the height of the tower of 13.5 degrees. He then could have moved 100 meters closer to point N and taken another measurement of the height of the tower. This measurement would be 14.8 degrees. Given this information, determine Mr. Dreyfuss’s distance from tower when he is standing at point N.

On the first part of a 317 mile trip, Leah averaged 58 miles per hour. She averaged only 52 mph on the last part of the trip because of an incrased volume of traffic. The total time of the trip was 5 hours and 45 minutes. Find the amount of time that Leah spent driving each speed.
