Answer:
History of mathematics
Several civilizations — in China, India, Egypt, Central America and Mesopotamia — contributed to mathematics as we know it today. The Sumerians were the first people to develop a counting system. Mathematicians developed arithmetic, which includes basic operations, multiplication, fractions and square roots. The Sumerians’ system passed through the Akkadian Empire to the Babylonians around 300 B.C. Six hundred years later, in America, the Mayans developed elaborate calendar systems and were skilled astronomers. About this time, the concept of zero was developed.

Hello!</h2>
The answer is:
The distance to over by Adam to get to the park is 108 miles.
<h2>
Why?</h2>
To solve the problem, we need to write two equations using he given information about the times and his speed.
So,
For the first equation we have: Travel to Disney Park


For the second equation we have: Travel back from Disnery Park



Then, if Adam covered the same distance going and coming back, we have:





We have that the speed when he was going to Disney Park was 27 mph.
Now, to calculate the distance, we need to substitute the obtained speed in any of the two first equations.
Therefore, substituting the speed into the second equation, we have:


Hence, we have that the distance that Adam should cover to get to the park is 108 miles.
Havea nice day!
Answer : 15 gallon per minute
$14 - covert 2/5 to a decimal (or percentage) = 0.4 (40%) and then multiply by 35.
