The answer is 12.
Since it took 42 hours to arrive at the vacation, and you were driving 50 miles per hour, the number of miles you would have driven (if you were driving nonstop) would be 2100. But since the mileage was only 1500, we subtract 1500 from 2100 getting 300. and dividing 300 by 50, we arrive at 12.

Answer:
plot (0,7) then move up 2 because it's positive and keep going up and down the same amount then put the line
Rate of fill-up = 1/44 = 1/44 * 77/77 = 77/3388
Rate of emptying = 1/77 = 1/77 * 44/44 =44/3388
Combined Rate of Fill-up = 77/3388 - 44/3388 = 33/3388 = 3/308
Time for combined fill-up = 308/3 = 102.6667 hours = 102 hours and 40 minutes
