It takes Virginia 9 minutes to ride her skateboard 3 blocks. Using this unit rate, how many minutes will it take Virginia to ride her skateboard 1 block?

3 minutes

Step-by-step explanation:

We can use ratios to solve

3 blocks           1 block

=

9 minutes         x minutes

Using cross products

3 * x = 9*1

3x = 9

Divide each side by 3

3x/3 = 9/3

x = 3

So the right answer is 3.
