A forest ranger is in a forest 2 miles from a straight road. A car is located c miles down the road. The forest ranger can walk 2 miles per hour in the forest and travel 3 miles per hour along the road. In the picture below, the forest ranger walks in a straight line to a point x unit from the end of the road on the left, and then along the road.
The total travel time for the ranger to get to the car is the sum of the travel time in the forest and the travel time on the road. Write the total time T as a function of x, using the letter c for the distance from the end of the road on the left to the car.
Toward what point on the road should the ranger walk in order to minimize the travel time to the car if...
(a) c = 8 miles? (Numerical Answer ONLY)
(b) c = 1/5 miles? Remember that the point must lie between the left end of the highway and the car. (Numerical Answer ONLY)

Harold wrote this equation to model the level of water in a pool over time. the variable x represents time in hours. f(x) = 3,500 - 225x which statements about the situation are true? check all that apply. the water level is rising. the water level is falling. the initial level of water in the pool was 3,500 units. the initial level of water in the pool was 225 units. the pool was empty after 14 hours. the water was 2,600 units high after 4 hours.
