OPEN RESPONSE QUESTIONS A .woled a Q1. Graphs: A cyclist rides 8.0 km north for 20 minutes at a constant velocity. After that, he takes a 5-minute break. Then, he turns around and starts riding south, continuing for 10 minutes, and covering a distance of 2 km at a constant velocity. He takes another 5-minute break. Finally, he rides north again for 10 km at a steady velocity, which takes him 20 minutes. (20 points) 1 . ii. Draw a picture with all the information. iii.
