Mariam has a goal of walking at least 10k steps each day. according to her pedometer she got 4500 steps in so far. there are 10 hours left in the day. how many steps will she need to get each hours for the est of the day to meet her goal?

To meet her goal of 10k steps per day, Mariam will need to walk 10,000 - 4,500 = <<10000-4500=5500>>5,500 more steps.

With 10 hours left in the day, Mariam will need to walk 5,500 / 10 = <<5500/10=550>>550 steps per hour for the rest of the day to meet her goal. Answer: \boxed{550}.
