Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
I will analyze two problems
see the attached figure to better understand the problem
Problem 1
The hypotenuse is the segment AB and the right angle is C
we know that
In the right triangle ABC
---> by SOH (opposite side divided by the hypotenuse)
substitute the given values

Remember that

substitute


Problem 2
The hypotenuse is the segment BC and the right angle is A
we know that
In the right triangle ABC
---> by TOA (opposite side divided by the adjacent side)
substitute the given values

Remember that

substitute


10:15
15/10
15/10*6/1=9 gallons
We take the ratio times the minutes to get the answer!
