Question

The speed of sound in water is measured to be 1485 m/s. what is this in mph?

Answer 1

Answer:

v =  3321.85 mph

Explanation:

Equivalences :

1 mile = 1609.34 m

1 hour = 3600 seconds

Data

v= 1485 m/s : speed of sound in water

Problem Development

To calculate the speed of sound in mph (mile / hour), we multiply by the conversion factors using the equivalences:

$v= (1485 \frac{m}{s} )*(\frac{1mile}{1609.34 m} )*(\frac{3600s}{hour})$

We cancel the units in seconds (s) and meters (m) to get the answer in miles per hour (miles / hour or mph)

$v=\frac{1485*3600}{1609.34} \frac{mile}{hour}$

v= 3321.85 mile/hour

v =  3321.85 mph

Answer 2

It will bw ugh 3500mph in
