Answer:Scale factor is 0.5
Step-by-step explanation:I will assume that:LM is the original distance
FG is the dilated distance
The dilation can be found using the following the general rule:dilated quantity = scale factor * original quantity
In the given, we have:dilated distance = 0.75 miles
original distance = 1.5 miles
Substitute with the givens in the above equation to get the scale factor as follows:0.75 = scale factor * 1.5
scale factor =
