Answer:
163 miles
Step-by-step explanation:
set up a ratio based on 49 miles in 1 hour (60 minutes):
let 'd' = distance in 3hrs, 20 min
3hrs, 20 min = 200 minutes
49/60 = d/200
cross-multiply:
60d = 9800
d = 163.3
 
        
             
        
        
        
that would be the letter d :)

Answer:
 b.  y = 3(x+2)^2 + 5
Step-by-step explanation:
The vertex form of a parabola is
y = a(x - h)^2 + k    where (h, k) is the vertex.
Here  h = -2 and k = 5 so the following could be the required equation\;
 y = 3(x+2)^2 + 5
