Time t=270 minutes=270/60=9/2 hours
distance s=63 miles
average speed v=s/t=63 ÷ $\frac{9}{2}$
=63× $\frac{2}{9}$
=14 miles/hour

Kinetic energy.

Explanation:

Hello,

In this case, we must take into account that kinetic energy is the energy associated with an object's motion. It is mass and velocity dependent by a directly proportional relationship.

On the other hand, potential energy is the energy associated with an object's position, thermal energy is the energy associated with heat addition or withdrawal.

By considering the aforementioned facts, kinetic energy is the suitable term to describe the energy of motion.

Best regards.
