Example 1.152 from Elementary Algebra, 1.10 Systems of Measurement

Systems of Measurement: example 1.152

Soleil was on a road trip and saw a sign that said the next rest stop was in 100 kilometers. How many miles until the next rest stop?

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution

$100 kilometers$

Multiply by a unit conversion factor relating km and mi. $100 kilometers \cdot \frac{1 mile}{1.61 kilometer}$

Simplify. $\frac{100 miles}{1.61}$

Divide. $62 ounces.$

Soleil will travel 62 miles.

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

The height of Mount Kilimanjaro is 5,895 meters. Convert the height to feet.

How did it go?
