Average velocity=total distance covered/total time taken
total distance covered=4 + 8=12 miles
total time taken=6 hours
Therefore
average velocity=12/6
=2 miles/hour
Hope this helps

Explanation:
Newton's second law of motion states F=ma which means force is equal to mass multiplied by acceleration which in simple terms means If you give mass force it will accelerate the concept of force in physics is any interaction that when unopposed will change the motion of an object.
 
        
             
        
        
        
Answer : The height is 188 meters  
Explanation :   When the cart reached at the end from top of hill then the cart have potential energy .
Given that, 
 Potential energy = 88435 J
Mass of cart = 48 kg
We know that,
The potential energy is



So, the height of the top is 188 meters.
