While on a beach vacation, Tasha makes a scale drawing of points of interest between two

alexdok [17]

Answer:

The distance between the two piers is 3 miles.

Step-by-step explanation:

If in Tasha's drawing 2cm represents 0.5 miles between the two piers, and the distance between the two piers in Tasha's drawing is 12cm.

The answer is found by the rule of three:

2 cm : 0.5 miles

12 cm : X

X = (12 * 0.5) / 2

X = 3 miles.

The distance between the two piers is actually 3 miles.
