the distance gone is
√(200^2+300^2) = 100√13 = 360.55
That was done in 1 hour, so it's also the plane's speed, in mi/hr.
Assuming it started at the airport...
After one hour in flight, an airplane is located 200 miles north and 300 miles west of the airport. What is the magnitude of the plane's velocity? Round your answer to the nearest mile per hour.
a) 22 miles per hour
b) 128 miles per hour
c )256 miles per hour
d) 361 miles per hour
I don't understand this! Thank you for your help!
