Answer: The required price is $3.19 per gallon.
Step-by-step explanation: Given that after an oil pipeline burst one morning gas prices went up by $2.20 per gallon. At the afternoon you bought 10 gallons of gas for $53.90.
We are to find the price per gallon before the oil pipeline burst that morning.
We will be using the UNITARY method to solve the given problem.
Cost of 10 gallons of gas = $53.90.
So, the cost of 1 gallon of gas will be
Therefore, in the morning before the oil pipe burst, the cost of 1 gallon of gas is given by
Thus, the required price is $3.19 per gallon.

<h3>What is velocity?</h3>Velocity is the direction at which an item is moving and serves as a measure of the rate at which its location is changing as seen from a certain point of view and as measured by a specific unit of time (for example, 60 km/h northbound). In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a basic idea. A physical vector quantity called velocity must have both a magnitude and a direction in order to be defined. Speed is the scalar absolute value (magnitude) of velocity; it is a coherent derived unit whose quantity is measured in metres per second (m/s or m/s1) in the SI (metric system).
