Jessica is taking a hike. she drinks 1 gal of water during the first part of the hike, and drinks 3 quarts of water during the second part of the hike. how much water does jessica drink in all?

She drank one and three fourths gallons of water, which is equal to seven quarts, which is congruent to fourteen pints, which is the same as twenty-eight cups, which finally is equal to two hundred twenty-four fluid ounces. There are four quarts in a gallon, two pints in a quart, two cups in a pint, and eight ounces in a cup. Hope this helps and have a nice day.

She drinks 7 quarts of water. 1 gallon is 4 quarts
