The speed of the wave would be 718.21 feet /second if a wave going if it travels a distance of one mile in 7.35 seconds.
<h3>What is speed?</h3>
The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object.
As given in the problem we have to find out how many feet per second is a wave going if it travels a distance of one mile in 7.35 seconds.
1 mile = 1609 meters
1 meters = 3.28084 feets
1609 meters = 1609 ×3.28084 feets
= 5278.87 feets
As given if the wave travels a distance of one mile in 7.35 seconds.
then the wave would travel at 5278.87 feet in 7.35 seconds.
speed of the wave = 5278.87 /7.35
= 718.21 feet /second
Thus, the speed of the wave would be 718.21 feet /second
