#9 is correct.
#10 is actually choice 2.
This is because the difference of logs with the same base (log(x)-log(y)) is equal to the log of the two numbers divided by each other, so log(x)-log(y) would equal log(x/y). In your case, log(15)-log(10) => log(15/10) => log(3/2), final answer.
Answer:

Answer:
linear
Step-by-step explanation:
We know the total distance and individual times, so we can sum and equate total distance.
Let
E=speed heading east
E+45=speed heading south
then
4(E+45)+6E=3370 miles
Solve for E:
4E+180+6E=3370
10E=3370-180=3190 mph
E=319 mph.
