Answer: B
Step-by-step explanation: The number line has tally marks up to 3, so 3 has to be divided by something, meaning A and C do not work. There are 9 total tally marks circled, so the equation equals 9, leaving B as the only possible answer. Also, there are three tally marks per whole number, so each tally is 1/3, which is equal to 2/6, further proving it is B.

The actual distance between park and movie theater is 68 miles, if the park and movie theater are 3.4 inches apart on a map and the map has a scale of 0.25 inch = 5 miles.
Step-by-step explanation:
The given is, 
              Park and movie theater are 3.4 inches apart
              Map has a scale of 0.25 inch = 5 miles
Step:1
             Formula to calculate the number of scales for distance between park and theater,
                                         
                                         
                                         = 13.6 
             number of scales for distance between park and theater  = 13.6 
Step:2
             Formula to convert distance inches to miles
                                        ×
 × 
                                       = 13.6 × 5
                                       = 68
             Actual distance between park and theater = 68 miles
Result:
            The actual distance between park and movie theater is 68 miles, if the park and movie theater are 3.4 inches apart on a map and the map has a scale of 0.25 inch = 5 miles.
