The contiguous United States are framed by three major bodies of water: the Atlantic Ocean on the east coast, the Pacific Ocean on the west and the Gulf of Mexico to the south. The Pacific also holds the Hawaiian Island chain. The Gulf stretches from Texas to Florida and also touches Alabama, Louisiana and Mississippi.
To find the epicenter (the point on the earth's surface where an earthquake begins) during earthquakes, one need to view the seismogram (a record of the ground motion), and at least two other seismographs recorded for the same earthquake. Other instruments such as a map, a compass for sketching circles on the map, a ruler, and a pencil will also be used.
The following are the steps of the triangulation process in the correct order to find the epicenter during earthquakes:
Step 1: Subtract the time of P wave arrival from S wave arrival.
Step 2: See what the time difference is equal to in distance on a seismic wave chart.
Step 3: Draw circles representing the distances from at least three seismograph stations to the epicenter on a map.
Step 4: Find the point where all 3 circles intersect, and you've found the earthquake's epicenter.

Explanation:
The distance between minutes of latitude is approximately 1.15 miles. There are 5280 feet in a mile, so there are 6072 feet in 1.15 miles. 1/60th of that is 101.2 feet.
The contrapositive of the conditional statement is option d: If the graph of two variables is not a linear function, then the two variables are not directly proportional.
<h3>What is the statement about?</h3>
To known a statement that is contrapositive, you will need to negate the hypothesis as well as the conclusion of the statement, and also switch their positions.
Hence:
- If two variables are directly proportional, so their graph is a linear function.
- If two variables are not directly proportional, so their graph is not a linear function.
Therefore, The contrapositive of the conditional statement is option d: If the graph of two variables is not a linear function, then the two variables are not directly proportional.
