Answer:
The ranger should walk <u>0.577 miles per hour</u> in order to decrease the time required to reach the car.
Step-by-step explanation:
Suppose the ranger reaches x miles from the end of the road which becomes the horizontal distance and the vertical distance is 1 miles. A right angle triangle can be obtained that shows the ranger walks along the hypothesis.
The distance left to reach the car is = 5 - x
To calculate total time taken, then the function becomes
In order to find the minimized time, differentiate the function T as follows
Equate the derivative to zero and obtained
Squaring both sides
The ranger should walk 0.577 miles per hour in order to decrease the time required to reach the car.
Δ ABC is an isosceles right triangle:∠ ABC =∠BCA = V45°
Δ ACE is also a right triangle (inscribed in half a circle.
The sum of its angles = 180° and ∠CAE + ∠ACE = 90 ;
∠ CAE + 57° *given) = 90°, then ∠ CAE = 33°
CALCULATE ∠ BAE:
∠ BAE = ∠BAC + ∠CAE
∠BAE = 45° + 33° = 78°

the answer is a=b
