None of the choices is correct.
If two runners take the same amount of time to run a mile, 
they have the same average speed.  But their velocities 
are not the same unless both runners begin and end their 
run at the same points.
Speed is   (distance covered) divided by (time to cover the distance).
Velocity is not.  It's something different.  
'Velocity' is not just a bigger word for 'speed'. 
        
                    
             
        
        
        
Answer:
It's D. The geothermal energy from Earth's core loses most of its heat before reaching the outer layer. The plates on the outer layer have been proven to be moving due to evidence such as earthquakes, volcanic eruptions, and tsunamis.
Explanation:
 
        
             
        
        
        
Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water.
        
             
        
        
        
Convert 38 ft/s^2 to mi/h^2. Then we se the conversion factor > 1 mile = 5280 feet and 1 hour = 3600 seconds.
So now we show it > 
Then we have to use the formula of constant acceleration to determine the distance traveled by the car before it ended up stopping.
Which the formula for constant acceleration would be > 
The initial velocity is 50mi/h 
When it stops the final velocity is 
Since the given is deceleration it means the number we had gotten earlier would be a negative so a = -93272.27
Then we substitute the values in....

So we can say the car stopped at 0.0134 miles before it came to a stop but to express the distance traveled in feet we need to use the conversion factor of 1 mile = 5280 feet in otherwards > 
So this means that the car traveled in feet 70.8 ft before it came to a stop.
