Question
A forest ranger is in a forest 2 miles from
and travel 5 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
straight road. A car is located c miles down the road. The forest ranger can walk 3 miles per hour in the forest
Highway
left, and then along the road.
Car
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,
Forest
T(x) =
Forest
Ranger
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 Abswer ONLY)
(b) c = 1/2 miles? Remember that the point must lie between the left end of the highway and the car. (Numerical Answer ONLY)
Think about the case when c is an arbitrary number of miles. Toward what point should the ranger walk in this case?
