(a)
How far is the plane from Orlando, after flying in this direction for 100 miles?
(a)
Answer to Problem 29E
122.75 miles far from Orlando
Explanation of Solution
Given information: Air Travel: The distance between Miami and Orlando is about 220 miles. A pilot flying from Miami starts the flight
Calculation:
Use the law of cosines to determine the pilot’s distance from Orlando.
Simplify and solve for the distance
Thus,
122.75 miles far from Orlando
(b)
How much farther is the flight than a direct route, if the pilot adjusts his course after 100 miles?
(b)
Answer to Problem 29E
2.7 miles farther
Explanation of Solution
Given information: Air Travel: The distance between Miami and Orlando is about 220 miles. A pilot flying from Miami starts the flight
Calculation:
Add the initial distance the pilot flew off course to the distance they were from Orlando at that point (the distance you just solved for).
Take that sum and subtract the distance of a direct flight from Miami to Orlando.
Thus,
2.75 miles farther
