An airplane flies 525 kilometers north in 1.25 hours. what is the airplane's velocity?

Speed = (distance covered) / (time to cover the distance)

Speed = (525 km) / (1.25 hrs)

Speed = (525/1.25) km/hr

Speed = 420 km/hr

Velocity = speed and the direction from start to finish

Velocity = 420 km/hr North

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

c) power lifting, will be your answer.
