To calculate the time it will take Rubio to reach his friend's house, we can set up a proportion:
2/3 mile = 16 minutes.
We want to find out how many minutes it will take him to walk 1 mile, so we set up the equation:
1 mile = x minutes.
In order to solve the proportion, we can cross multiply:
2/3 * x = 1 * 16.
Simplifying this equation, we get:
2x/3 = 16.
To isolate x, we can multiply both sides of the equation by the reciprocal of 2/3, which is 3/2:
(2x/3) * (3/2) = 16 * (3/2).
Simplifying further:
x = (16 * 3) / 2.
x = 48/2.
x = 24.
So, it will take Rubio 24 minutes to walk to his friend's house.
