Determine how far sound travels in 55 minutes. Express your answer in feet. You may use 760 mph as the speed of sound.

distance=speedsound*time

write time in hours, or 55/60 hr

You will have to then convert miles to feet.

To determine how far sound travels in 55 minutes, we can use the formula: distance = speed of sound x time.

Given that the speed of sound is 760 mph, we need to convert the time from minutes to hours. Since there are 60 minutes in an hour, 55 minutes is equal to 55/60 hours, which simplifies to 11/12 hours.

Now, we can substitute the values into the formula:

distance = 760 mph x (11/12 hr)

To convert miles to feet, we need to know that 1 mile is equal to 5280 feet. So, we can multiply the distance in miles by 5280 to get the distance in feet.

distance = (760 mph x 11/12 hr) x 5280 ft/mile

Simplifying the equation further:

distance = (760 x 11 x 5280) / (12)

Calculating:

distance = 420720 ft

Therefore, sound travels approximately 420,720 feet in 55 minutes.
