Answer: B
Step-by-step explanation:
 
        
             
        
        
        
Solve for the two velocities:
with the current = 48/6 = 8 mph
against the current = 48/8 = 6 mph
bv= boat velocity in still water
cv = current velocity
A) bv -cv = 6mph
B) bv + cv = 8mph
Adding both equations
2 * bv = 14 mph
boat velocity = 7 mph
current velocity = 1 mph
