Hey! Hope that I can help. 1 gallon = 4 quarts, so 12 x 4 = 48 quarts.

Answer:
b. How many ways arc there to go 12 miles? 
≡ p(12) = 25
c. How many ways arc there to go 20 miles? 
≡ p(20) = 131
d. How many ways arc there to go 22 miles?
≡p(22)  199
Step-by-step explanation:
a) supposed you walked for the first hour. Then you would have travelled 3 miles. if you jogged you would have covered 5miles and if you run you would have covered 10miles. now you have to decide how to run the rest miles from the n miles.
Thus, the number of ways one can cover n miles will be given by the recurrence relation
p(n) = p( n-3) + p( n-5) + p( n - 10)
now to solve the rest of the question, let us make a table which provides the number of ways for n = 1  to 22.

b. How many ways arc there to go 12 miles? 
≡ p(12) = 25
c. How many ways arc there to go 20 miles? 
≡ p(20) = 131
d. How many ways arc there to go 22 miles?
≡p(22)  199
