Hailey drove 12 miles to Hong Kong, but on her map the same distance is represented by 2 inches. What scale is the map using? \(1 \, inch \, = \, 6 \, miles\)

\(1 \, inch \, = \, 6 \, miles\)

\(1 \, inch \, = \, 7 \, miles\)

\(1 \, inch \, = \, 5 \, miles\)

\(1 \, inch \, = \, 6 \, miles\)

\(1 \, inch \, = \, 3 \, miles\)

An oil rig worker drives 8 miles to an oil rig. Once she arrives she looks at her map and notices that it doesn't have a scale written down. She measure the distance she just drove as 4 inches. What is the scale of the map? \(1 \, inch \, = \, 2 \, miles\)

\(1 \, inch \, = \, 2 \, miles\)

\(1 \, inch \, = \, 4 \, miles\)

\(1 \, inch \, = \, 5 \, miles\)

\(1 \, inch \, = \, 1 \, mile\)

\(1 \, inch \, = \, 2 \, miles\)
