the velocity of sound in air is 332m/s. if the unit of length is km and the unit of time is hour,what is the value of velocity?

• physics -

332m/s * 1km/1000m * 3600s/1hr=?

• physics -

Multiply 332 m/s by
(1 km/1000m)*(3600s/1hr)

I get 1195 km/hr
It's also 743 mph

• physics -

1.20 * 10^3km/hr
