How long is the actual trail?
A. 1 and 3/4 miles
B. 2 and 5/8 miles
C. 3 and 1/2 miles

D. 7 and 7/8 miles

Answer 1

Answer:  C. 3 and 1/2 miles

Step-by-step explanation:

Convert the scale to a unit measure.

3 inches to 2 miles.  Divide both numbers by 3.  

1 inch = ²/₃ mile

Multiply the inches by the unit scale.

5¹/₄ × ²/₃   change to improper fraction ²¹/₄ × ²/₃ = ⁴²/₁₂  3⁶/₁₂

That is  3 and 1/2 miles
