Quizplus · Accepted Answer

To convert miles per hour to meters per second, we need to multiply by a conversion factor of (1609 meters/1 mile) and then divide by (3600 seconds/1 hour).
Therefore, 
50 mi/h = (50*1609 meters/1 mile) / (3600 seconds/1 hour)
= 22.352 meters/second
The closest answer choice to this value is C) 22 m/s, so it is the best choice.
