Chapter 2: Q25. (page 66)

For Exercises 25and 26, use the following information.

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

How far does a sound travel underwater in 5seconds?

Short Answer

Expert verified

The sound will travel 7200 meters underwater in 5 seconds.

Step by step solution

01

– Given information.

The given equation is:

y=1440x

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

02

– 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=14405

03

– Solve the equation.

Simplify the above equation to find the required value.

y=1440(5)=7200

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