Answer:

3.75 miles

Explanation:

You want to know the number of miles represented by 6 km, when the relationship is 1.6 km = 1 mile.

Conversion factors

Anytime measures are related by a constant conversion factor, the values of the measures in one unit are proportional to the values expressed in a different unit. That is, the ratio of km to miles is a constant.

Application

We can let d represent the distance between the school and the park.

miles / km = (1 mi)/(1.6 km) = d/(6 km) . . . . miles and km are proportional

Multiplying by 6 km, we get ...

d = (6 km)(1 mi)/(1.6 km) = (6/1.6) mi ≈ 3.75 mi

The school and the park are 3.75 miles apart.
