enter your response here days.
​(Simplify your answer. Type a whole​ number, proper​ fraction, or mixed​ number.)

Answer 1

Convert to fractions: 2 1/2 = 5/2 and 4 3/4 = 19/4. Their daily total = 5/2 + 19/4 = 10/4 + 19/4 = 29/4 gallons/day.
Days = 58 ÷ (29/4) = 58 × 4/29 = 8.

The water would last for 8 days.
