Airplane traveling at 240 mph is descending at an angle of depression of 5. How many miles will the plane descend in altitude in 4 minutes

You just have to find the speed in the downwards direction. Just realize that the speed is vector which can be split up in components. The total speed is then the hypotenuse of a right right triangle and the downward speed is the opposite side. Thus sin(5deg)*240=20.917. then just multiply by the time traveled 20.917*4/60=1.394 miles|dw:1386355290833:dw|
