B. 1.5 miles

C. 450 miles

D. 150 miles

C

Step-by-step explanation:

3 inches would be 3 times 150 miles or 450 miles.

6 problems per hour

Step-by-step explanation:

The first hour, she completed 12 problems, but for the last 12 it took her 3 hours.

                         Time Space 1:  1 hour for the first 12.

                          Time Space 2: 3 hours for the last 12.

Since we already know that there are 24 problems total, and 12 plus 12 equals  24; we can add the hours together ( 1 + 3 = 4 )

                             24 problems took 4 hours to complete.

             Divide the 24 problems by the 4 hours to get the basic unit of

                                6 problems per hour which is the answer
