subtract 4x from both sides and you get y=4x

y varies directly with x. When x is 1, y is 1/4. when x is 4, y is 1. when x is 8, y is 2. So on and so on. Sorry if this is confusing. Direct variations is one of my weak points

Answer:

3.1 inches

Step-by-step explanation:

The scale is

1/8 in = 10 miles
1/8*8 in = 10*8 miles
1 in = 80 miles

Then

x in = 248 miles

Cross multiplication

x - 248
1 - 80
x = 248/80 = 3.1 in
