tatyana61 [14]

The distance in miles between each wave and the next is 1.14 miles. The correct option is c. 1.14 miles

<h3>Calculating Wavelength </h3>

From the question, we are to determine the distance in miles between each wave and the next. That is, we should determine the wavelength.

From the formula,

v = fλ

Where v is the velocity

f is the frequency

and λ is the wavelength

We can write that

λ = v/f

From the given information,

v = 600ft/min

Now, we will determine the frequency, f

f = 1/T

Where T is the period

From the given information,

T = 10 minutes

Thus,

f = 1/10 = 0.1 min⁻¹

Now, we can determine the wavelength

λ = v/f

λ = 600/0.1

λ = 6000 ft

Now, convert 6000 ft to miles

NOTE: 5280 ft = 1 mile

∴ 6000 ft = 6000/5280 miles

6000 ft = 1.14 miles

Hence, the distance in miles between each wave and the next is 1.14 miles. The correct option is c. 1.14 miles
