D. Measurements with Multiple Parts

Some measurements, such as feet and inches or hours and minutes, are commonly reported together. For example, someone's height may be reported as 5 feet and 9 inches instead of 69 inches. These measurements can be thought of as separate measurements added together.

For example, 3 hours and 14 minutes = 3 h + 14 min.

To convert a measurement with multiple parts into a single unit, just use unit conversions to express all parts in terms of the same unit and then add the values.

 

Example 1

Convert 2 hours and 24 minutes into minutes.

Begin by converting the 2 hours into minutes.

Now add the two measurements.
