The speed of sound in air at sea level at 32 degrees Fahrenheit is 1088 ft/s. If that represents only 22.04% of the speed of sound in ice-cold water, what is the speed of sound in ice-cold water, to the nearest whole number?

what i did:
22.04/100 = 32/x
i set up this proportion, is this correct?

No. The temperature really makes no difference. What you want is

1088 = 0.2204 x

where x is the speed of sound in cold water.

Yes, you set up the proportion correctly. To find the speed of sound in ice-cold water, you can use the following proportion:

(22.04 / 100) = (32 / x)

To solve this proportion, you can cross-multiply:

x * 22.04 = 32 * 100

Now, divide both sides of the equation by 22.04 to find the value of x:

x = (32 * 100) / 22.04

Evaluating the right side of the equation, we get:

x ≈ 145.05

Therefore, the speed of sound in ice-cold water is approximately 145 ft/s (to the nearest whole number).

Yes, you have set up the proportion correctly. To find the speed of sound in ice-cold water, you can use the proportion:

(22.04/100) = (32 / x)

To solve for x, the speed of sound in ice-cold water, you can cross-multiply:

22.04 * x = 100 * 32

Now, you can solve for x by dividing both sides of the equation by 22.04:

x = (100 * 32) / 22.04

Evaluating the right side of the equation gives:

x ≈ 145.65

So, the speed of sound in ice-cold water, to the nearest whole number, would be 146 ft/s.
