Jeannie discovered that the ratio of kilometers to miles is 1 to 0.6. When her family was driving in Canada, she saw a sign that said it was 80 kilometers to Moncton. How many miles do they have to drive to get to Moncton?

40 miles
48 miles
64 miles
75 miles

1 answer

To convert kilometers to miles using the given ratio, we can set up a proportion based on the ratio of kilometers to miles.

The ratio states that: \[ \text{kilometers} : \text{miles} = 1 : 0.6 \]

This means that for every 1 kilometer, there are 0.6 miles. To find how many miles correspond to 80 kilometers, we set up the equation: \[ \text{miles} = \text{kilometers} \times 0.6 \] Substituting 80 kilometers into the equation: \[ \text{miles} = 80 \times 0.6 = 48 \text{ miles} \]

Thus, Jeannie and her family need to drive 48 miles to get to Moncton.
