Answer:

6.4 miles

Explanation:

We use the distance formula to find the distance, d, between points (2, 8) and (-1, 5).


d = √((x_2 - x_1)^2 + (y_2 - y_1)^2)


d = √((-1 - 2)^2 + (5 - 8)^2)


d = √((-3)^2 + (-3)^2)


d = √(9 + 9)


d = √(18)


d = 3√(2)

The distance is 2√3 grid squares.

Now we convert this distance to a real distance using the conversion factor (1.5 mile)/(1 grid square) = 1.

2√3 grid squares × (1.5 mile)/(1 grid square) = 6.36396 miles

Answer: 6.4 miles
