If the average speed of a helium atom at a certain temperature is 1220 m/s, what is the speed in miles per hour? (1 mi = 1609 m)

Respuesta :

1 mile = 1609 m

and 1 hour = 3600 seconds

so we can convert 1220 m/s into miles per hour as following:

(1220 m/s) ×( 3600 sec/hour) ÷ (1609 m/mile)

= 2729.65 mile/hour
