Honi is looking at a map with a scale of 1/4 in. = 20 miles. she measured the distance from niceville to live oak as 2.5 in. she found the actual distance between niceville and live oak by following these steps:
step 1: set up a proportion 1/4 /20 = 2.5 x
step 2: cross multiply (20)(2.5) = ( 1/4 )(x)
step 3: simplify 50 = 1/4 x
step 4: solve for x x = 250 miles
in which step did honi make a mistake?
a. step 1
b. step 2
