Are they asking for the surface area?
When you say "at the same ratio", you mean that you consume the same amount of gas for the same amount of miles.
We know that everytime you drive 75 miles, you use 3 gallons of gas.
Since 12 gallons of gas is four times 3 gallons of gas, if the ratio remains the same, you can drive four times the distance:
You drive 75 miles, and use 3 gallons.
You drive 75 more miles (so you are at
miles) and use 3 more gallons, so you use
gallons.
You drive 75 more miles (so you are at
miles) and use 3 more gallons, so you use
gallons.
You drive 75 more miles (so you are at
miles) and use 3 more gallons, so you use
gallons, and you're done.
Answer:

Step-by-step explanation:
The given absolute value function is

This is the base or the parent function.
The transformation
will shift the parent function b units to the left and c units up.
From the question, b=4 units and c=2 units.
The new equation is 
22.5 times 1,000,000
22,500,000 in mm
22,500 meters and
22.5 kilometers
