  The odometer of a new automobile functions improperly and registers only 2 miles for every 3 miles driven. If the odometer indicates 48 miles, how many miles has the automobile actually been driven?

  (B) 72

  (C) 64

  (D) 32

  (E) 24

  The correct answer is B

  Explanation

  In this problem, you are told that the odometer registers only 2 miles for every 3 miles driven. So the ratio of miles registered to miles driven is 2 to 3 or 2 over 3. This can be expressed as

  odometer reading over actual miles = 2 over 3

  If the odometer indicates 48 miles, the actual miles can be found using using the above relationship as follows:

  48 over x = 2 over 3 and 2x = 144 and x=72

  So if the odometer indicates 48 miles, the actual number of miles driven is 72.
