Answer:
17.67 mpg
Step-by-step explanation:
The fuel efficiency is given by :

We need to find the fuel efficiency for a speed of 30 mph
Put the value of s equals 30 mph in the above equation.

So, the required fuel efficiency is equal to 17.67 mpg.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
1) ∠WVZ and ∠VWX are right angles & VX = = WZ      Given
2) WV = VW                                                                      Reflexive property
3) ΔWVZ ≅ ΔVWX                                                           HL
4) ∠Z = ∠X                                                                       CPCT
CPCT --> Corresponding parts of congruent triangle.
