she ran 2/3 mile in 1/6 hour, which means she ran 1/3 of a mile in 1/12 of an hour
so 1 mile would be run in 1/12 + 1/12+ 1/12 ( = 1/4 of an hour)
there are 4 quarters to an hour so she is running at 4 miles per hour
Answer:
y = -1, x = -2
Step-by-step explanation:
First, multiply the top equation by 2 to make 3x become 6x:
6x - 8y = -4
Second, multiply the bottom equation by 3 to make -2x become -6x:
9y - 6x = 3
Add the two equations together, and you get:
y = -1
Plug in y as -1 into the first or second equation:
3x - 4(-1) = -2
OR
3(-1) - 2x = 1
x = -2
2.6 gallons per hour x 16 hours = 41.6 gallons
