Before her hike, Lara filled her water bottle with 4 cups of water. During the hike, she drank about 10 fluid ounces every hour. Afterward, she had about 12 fluid ounces left. How many hours did she hike?

Lara hiked for 2 hours.

A cup contains 8 fluid ounces so the total number of ounces that Lara had before the hike was:

= Number of cups x fluid ounces per cup

= 4 x 8

= 32 fluid ounces

After the hike, Lara was left with 12 fluid ounces which means that she consumed:

= 32 - 12

= 20 fluid ounces

She drank 10 fluid ounces per hour so the total number of hours she hiked were:

= Number of fluid ounces consumed / Fluid ounces per hour

= 20 / 10

= 2 hours
