The property of real numbers illustrated by the equation 16(3t+4v)=48t+ 64v.
 Therefore, the answer is: Distributive property.
 As you can see, you have the equation 16(3t+4v), and when you apply the Distributive property, you obtain:
 16(3t+4v)
 (16)(3t)+(16)(4v)
 48t+64v
        
             
        
        
        
Answer:

Answer:
1400 miles
Step-by-step explanation:
Speed is the time rate of change of distance. It is the ratio of distance to time and is given by the equation:

 plane averaged 400 mph on a trip going east, but only 280 mph on the return trip. 
The time spent (t₁) in going east is given by:

The time spent (t₂) in going east is given by:

The total time (t) = t₁ + t₂
t = t₁ + t₂ = 8.5 hours

Therefore the one way distance is 1400 miles
