Question

Some birds migrate 20,000 miles. If 1 mile is 1.6 kilometers, calculate the distance these birds fly in kilometers.

Answer 1

32000 kilometers

Step-by-step explanation:

In order to convert from miles to kilometers, we need to use a conversion factor. In other words, we put miles in the denominator and kilometers in the numerator, as follows:

• 20000 miles *
  `(1.6km)/(1mile)` = 32000 kilometers

That way the units for miles cancel each other, leaving the equivalent amount in kilometers.
