Answer:

y=45x

y represent the distance traveled by the car in x gallons of gas.

Step-by-step explanation:

Given:

A car travels 45 miles  on one gallon of gas.

We need to calculate distance covered by the car in x gallons of gas.

Let y represent the distance traveled by the car in x gallons of gas.

We know that distance traveled by the car directly varies with the amount of gas.

So, we havey ∝ x

Thus y=kx

where k represents the distance traveled by car in 1 gallon of gas.

From the data given we know k=45

So, the expression to find the distance the car can travel using x gallons of gas is written as:

y=45x
