My answer: Juan and Rita both rode bicycles from the park to Main Street. The graphs below represent time and distance for each student's ride. Juan rode more slowly because if you look at the graphs it shows that Rita rode 8 blocks in 8 minutes and Juan rode 8 blocks in 16 minutes which is longer than 8 minutes meaning Juan was slower.

    Hint to Help: Putting numbers and letters with answers doesn't help. Everyone most likely has different test, so that is giving everyone a free sheet of wrong answers. Helpers, if your gonna help, be a great one and give answers that were proven correct. Thank you for understanding.
