Answer :
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:
[tex]v= (1485 \frac{m}{s} )*(\frac{1mile}{1609.34 m} )*(\frac{3600s}{hour})[/tex]
We cancel the units in seconds (s) and meters (m) to get the answer in miles per hour (miles / hour or mph)
[tex]v=\frac{1485*3600}{1609.34} \frac{mile}{hour}[/tex]
v= 3321.85 mile/hour
v = 3321.85 mph
