761 mph at sea level

Mach 1 is the speed of sound at 15 °C and is 761 mph.
As the speed of sound increases as temperature increases, Mach 1 is temperature dependent.

We can say that Mach 1 = 761.5 mph at sea level.

1 mile/ 9 seconds 60 seconds are in a minute so multiply by 60 seconds/ 1 minute to get 60 miles / 9 minutes there are 60 minutes in an hour so multiply by 60 minutes/ 1 hour to get 3600 miles/ 9 hours then just divide 3600 by 9 to get it over 1 hour. So in the end it would be 400 miles per hour. In conversions you just need to look at what you have and decide what you need. Then you just multiply by one to get it to what you want because notice that 60 seconds and one minute are the same thing so they equal 1. You don't change the numerical value of the original ratio just what their measurements are so you end up multiplying by one. You want the seconds to cancel so since the seconds are on the bottom in the first one you put it on top in the second one so that they can cross cancel. Just work it out one part at a time.

Hey Nick...That answer is going to vary depending on the elevation and the air temp.
At sea level with the air temp 60degrees....that speed will be 761.2 miles per hour.....However we can assume a plane will be flying higher that sea level....At approx 31,000 ft with the air temp @ -52 degrees Mach One is 675 miles per hour .....Quite a difference.....
I hope this helps....

761.2 in a standard atmoshpehere.
Mach is affected by temperature
