Your improvements are very noticable and will be appreciated by the learners. I like the way that you highlight (in colour) items such as the tooth ratios, speed ratios, etc. I use this method all of the time. Therefore, even in your examples, as you display the Given information, I would highlight it as well as the numbers from the original question. In this way the students can know exactly where you are picking the information from. Another nice thing to do (as a future consideration) is to provide the opportunity for students to obtain hints during the solving of a problem. This may be beyond the scope of your exercise but if you do it once, you may find that it is easy to include in future learning objects. Once again, this is a fantastic tool for students and I appreciate the work that you put into it. It is a definite keeper. Do you know if there will be an extension to this one? For instance; compound gear ratios, compound machine ratios (motor to gear box to pulley), learning the direction of rotation in a compound gear set, etc.)?
