Question

(Use the Pythagorean theorem to answer the question.) An airplane takes off going straight west at 340 km/h for 1 hour, then turns and heads south for another hour at 360 km/h before reaching its final destination. What is the airplane's displacement?

Answer 1

a^2+b^2=c^2, 340^2+360^2=c^2, 115600+129600=c^2, 245200=c^2, 495.2=c

Answer = 495.2 km
