There is a mistake 9,12,13 is not a right triangle. but 9,12,15 is. IF you use this triangle instead, then the area of the 13,14,15 triangle is the sum of the area of the other two triangles.
1.04 ^ 1/12 = 0.086666666
or
1.04 ^ 1/12 = 13/150
1/2 of an hour is = 30
288 / 4.30=67
The answer is 67 miles per hour.
(45 gal/day) x (31 day/Dec) =
(45 x 31) (gal/Dec) = <em>1395 gallons</em> per December .
Choice-B is closer to that figure than Choice-A is,
but they're both poor estimates.
