Answer 1

Answer:

The answer to your question is: 30 miles can the car travel.

Step-by-step explanation:

Data

gasoline used = 11 1/2 gal

distance = 345 mile-trip

distance travel with 1 gal = ?

Process

Convert 11 1/2 to a improper fraction    11 1/2 = 23/2

Rule of three

                            23/2 gal -----------------------  345 miles

                              1 gal      ----------------------   x

                          x = (1 x 345) / 23/2

                          x = 345 / 23/2

                          x = 690/ 23

                          x = 30 miles
