This word problem set involves solving distance (rate x time = distance) problems using one variable. There are 10 problems of increasing difficulty with full written out solution keys. I have students use a grid method for organizing the information which is demonstrated in the answer key. These problems involve solving multistep equations, some with variables on both sides. One method for use could be to demonstrate 5 problems in class and have the students solve the remaining 5 for homework. In a 45 minute block, I often introduce 2 types of word problems at a time. If your students are just beginning to solve word problems, I have a free graphic organizer that might help.
