At 7:57 am, Flight 501 is at an altitude of 6 miles above the ground and is on a direct approach (i.e., flying in a direct line to the runway) towards Manhattan Airport, which is located exactly 8 miles due north of the planes current position. Flight 501 is scheduled to land at Manhattan Airport at 8:00 am, but, at 7:57 am, the control tower radios the plane and changes the landing location to an airport 15 miles directly due east of Manhattan Airport. Assuming a direct approach (and negligible time to shift direction), by how many miles per hour does the pilot have to increase her speed in order to arrive at the new location on time?
a) 5 (squarerrot 13) - 10 miles/hr
b) 100 miles/hr
c) 100(squareroot 13) - 200 miles/hr
d) 200 miles/hr
e) 100 (squareroot 13) miles/hr
