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.
Count by 10s after 27 so continue with 37, 47, 57 until you get past at least 100, which should be 8 times. Therefore it would take 8 weeks of allowance to reach $107
Y = 8/cos60 = 16
x = sqr(16^2 + 8^2) = 8sqr(3) = 13.86 approx
The answer is (5,4). X being the run (5), and Y being the rise (4).
