Question

For Exercises $25$and $26$, use the following information.

When a sound travels through water, the distance $y$in meters that the sound travels in $x$seconds is given by the equation $y=1440x$.

How far does a sound travel underwater in $5$seconds?

Short answer

The sound will travel 7200 meters underwater in 5 seconds.

Step-by-step solution

– Given information.

The given equation is:

$y=1440x$

Where y is the distance in meters that the sound travels in x seconds.

– Substitute the given value in the function.

Substitute x=5 in the given equation to find the distance traveled by the sound underwater in 5 seconds.

$y=1440\left(5\right)$

– Solve the equation.

Simplify the above equation to find the required value.

$\begin{array}{l}y=1440\left(5\right)\\ =7200\end{array}$

Thus, the sound will travel 7200 meters underwater in 5 seconds.
