Chapter 6.3 Problem 119
Question
From a parking lot, you want to walk to a house on the beach. The house is located 1500 feet down a paved path that parallels the ocean, which is 500 feet away. See the illustration. Along the path you can walk 300 feet per minute, but in the sand on the beach you can only walk 100 feet per minute. The time T to get from the parking lot to the beach house can be expressed as a function of the angle u shown in the illustration and is T1u2 = 5 - 5 3 tan u + 5 sin u , 0 6 u 6 p 2 Calculate the time T if you walk directly from the parking lot to the house. 3Hint: tan u = 500 1500 .4

From a parking lot, you want to walk to a house on the beach. The house is located 1500 feet down a paved path that parallels the ocean, which is 500 feet away. See the illustration. Along the path you can walk 300 feet per minute, but in the sand on the beach you can only walk 100 feet per minute. The time T to get from the parking lot to the beach house can be expressed as a function of the angle u shown in the illustration and is T1u2 = 5 - 5 3 tan u + 5 sin u , 0 6 u 6 p 2 Calculate the time T if you walk directly from the parking lot to the house. 3Hint: tan u = 500 1500 .4

Two oceanfront homes are located 8 miles apart on a straight stretch of beach, each a distance of 1 mile from a paved path that parallels the ocean. Sally can jog 8 miles per hour on the paved path, but only 3 miles per hour in the sand on the beach. Because a river flows directly between the two houses, it is necessary to jog in the sand to the road, continue on the path, and then jog directly back in the sand to get from one house to the other. See the illustration. The time T to get from one house to the other as a function of the angle u shown in the illustration is T1u2 = 1 + 2 3 sin u - 1 4 tan u 0 6 u 6 p 2
