Answer: 21120 feet.
Step-by-step explanation: We start with the fraction 1/180, found by putting 20 seconds over one hour. Then, we need to get the amount of miles the speed of sound travels in 20 seconds. We can use the fraction above as a ratio to get it. 720/1 x 1/180 = 4 miles. Then, we'll just do 4 times 5280, which is 21120.
The location of the treasure on the treasure map is (b) (7.6,8.8)
The ratio is given as:
The coordinates of the rock and the tree are:
The x and y coordinates of the location of the treasure are:
So, we have:
Hence, the location of the treasure is (b) (7.6,8.8)

<h3><u>The variable is equal to 20.</u></h3>
6w + 30 + w = 4w + 90
Subtract 30 from both sides.
6w + w = 4w + 60
Combine like terms.
7w = 4w + 60
Subtract 4w from both sides.
3w = 60
Divide both sides by 3.
w = 20
