If a migrating loon flies at an average speed of 19 m/s, what is its average speed in mi/hr?
zlopas [31]

Unit conversion is a way of converting some common units into another without changing their real value. The average speed of the migrating loon flies is 45.5019 miles/hr.

<h3>What is Unit conversion?</h3>

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimeter is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

Given that migrating loon flies at an average speed of 19 m/s. Now, since 1 meter is equal to (1/1609.34) miles and 1 second is equal to (1/3600) seconds. Therefore, we can write the speed as,

\rm Speed = 19\ \dfrac{meter}{second}\\

         =19 \times \dfrac{\frac{1}{1609.34}\rm\ miles}{\frac{1}{3600} \rm\ hours}

         = 19 × (3600/1609.34) miles/hr

         = 42.5019 miles/ hr

Hence, the average speed of the migrating loon flies is 45.5019 miles/hr.
