A runner ran 24 km in 2 hr; he then rested for 1 hr. He then ran another 48 km in 4 hr. What is the runner’s average speed?
What is 10.29 km/hr
If the forces on an object are balanced, the object will stay at rest or continue moving in the same direction at the same speed. If the forces on an object are not balanced, the net force will increase the object’s speed, decrease its speed, and/or change its direction of motion.?

The acceleration of an object is equal to the net force on the object divided by the object’s mass.
What is Newton's second law
