What is the speed of sound in miles per second

Answer:

344.6 m/s

Explanation:

Speed of sound, v = 0.214 miles per second

The relation between the unit of distance mile and the unit of distance km is given in the question.

0.621 mile = 1 km

As we know that 1 km  = 1000 m

So, 0.621 mile = 1000 m

1 mile = 1000 / 0.621 m = 1610.3 m

0.214 miles = 1610.3 x 0.214 = 344.6 m

So, the speed of sound in metre per second is 344.6 m/s.
