The reasonable range in this situation is between 250 and 300 miles, so the correct option is B, 275 (average)

which of the following would be a reasonable range for this situation?

We know that the car travels 25 miles on one gallon of gas, so we can define the function:

d(x) = 25*x

Where d is the distance travelled when x gallons of gas are used.

We know that between 10 and 12 gallons are used, then the range of distances is give by:

d(10) = 25*10 = 250

d(12) = 25*12 = 300

Then the reasonable range is (250, 300) or, between 250 and 300 miles.
