Bret is planning a long hike. He figures that he will need at least 0.75 liters of water for each hour on the trail. He also wants to have 1.8 liters of water in reserve at all times. If he can only carry 9 liters of water maximum, how many hours can he hike?

Respuesta :

5.40 is what I got so about 5 hours. You subtract first (9-1.8) Then what you get which was 7.2 you multiply it by 0.75. to get 5.40 (you multiply because its a decimal.)
