The speed of the sound in air at room temperature is 343 m/s. Calculate this speed in miles per hour.
hjlf

Convert metres to feet:

343m*3.28f = 1,125.04ft/s

There are 3600 (60 seconds * 60 minutes) seconds in an hour. Therefore, use this number to convert to an hour.

1,125.04ft*3600s = 4,050,144 ft/h

Now, since you asked for miles, convert to miles (5280 ft in a mile):

4,050,144ft/5,280m = 767.072mph

That is your answer! Hope I helped. :)
