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 3 miles per hour in the forest and travel 4 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. Highway 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. (x) - Toward what point on the road should the ranger walk in order to minimize the travel time to the car if.. (a) c - 10 miles? (Numerical Answer 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 miles. Toward what point should the ranger walk in this case?

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
