Roger said that there are two routes from his home to his work. His usual route is 28.3 miles long. A shortcut that he sometimes takes is 19.7 miles long. Approximately how much longer is
his usual route than the shortcut?

OA 10 miles
OB 8 miles
OC 6 miles
OD 5 miles

The answer is B. 8 miles

Step-by-step explanation:

First you take the original route length and subtract the shortcut route length from that. Next, since the problem has the key word, Approximately, we would find the closest answer to our difference.

28.3 - 19.7 = 8.6

8.6 = 8

8 miles
