When multiplying conversion factors, make sure the only remaining units are the desired units.
322 000m/h
Practice makes perfect
We want to express 322 kilometers per hour in meters per hour.
322 km/h= m/h
This means that we need to change kilometers per hour into meters per hour. To do so, we will use the fact that 1 kilometer is equal to 1000 meters. Let's write this relationship as a unit ratio.
1000 m/1km
To perform the conversion, we need to multiply the speed in kilometers per hour by the unit ratio or its reciprocal. Remember, we want to arrange these ratios such that every unit we do not want gets canceled out, and only the units that we want will remain.
We found that the falcon can fly at a speed of 322 000 meters per hour.
