If 1 mile equals 1.6 km, the distance these birds fly is 32000km.
Here we have,
Total miles = 20,000
Given, 1 mile = 1.6 kilometer
Thus, total km travel = 20000 x 1.6
Total km travel = 32000 km
A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement.
Thus, some bird species travel 20,000 miles. These birds travel 32000 kilometers if a mile is equal to 1.6 kilometers.
