for # 18 the part when you said that the time she traveled in the evening was one hour minus the time she traveled in the morning. why won't it work if you say that in vice versa. couldn't you also say the the time she traveled in the morning is one minis the time she traveled in the evening, i tried it that way and my answer comes out as 12 miles for her morning time. any help would be appriciated
