Answer
320 )(5/8) = 200
Explanation
To solve this question, we need to apply a unit conversion problem by using proportions. A simple proportion equation comes from the basic conversion given in the question, which tells us that 8 kilometres equals 5 miles. To find out how many miles 320 kilometres is, we have to multiply the amount of miles in 8km, by the measurement of kilometres we're trying to convert, divided by 8.
