What is the scale factor in the dilation?

3

Step-by-step explanation:

Use sides with a whole integer for the original shape and the dilated one.

Use the bottom side, which stretches out to 3 and has a dilated size of 9.

You put the change over the original. 9/3 = 3

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
