Answer 1

4.4 L

Explanation:

Given:

Water required for every 2 miles = 1 quart

Total distance traveled = 15 km

Now,

1 km = 0.621 miles

thus,

15 km = 0.621 × 15 = 9.32 miles

Therefore,

Quarts of water required for 15 km (9.32 miles) =
`\frac{\textup{9.32}}{\textup{2}}` = 4.66 quarts

also,

1 quart = 0.95 L

therefore,

4.66 quarts = 4.66 × 0.95 = 4.427 ≈ 4.4 L
