Marjam has a goal of taking at least 10,000 steps today. According to her pedometer she got 2500 steps in the morning. There are 10 hours left in the day. How many steps will she need to get each hour(assume she walks the same number of steps each hour) for the rest of the day to meet her goal? Solve this problem which graph most clearly communicates the solution. On a number line
To find the number of steps she needs to get each hour for the rest of the day, we can subtract the number of steps she has already taken from her goal: 10,000 steps - 2,500 steps = 7,500 steps.
Since there are 10 hours left in the day, she needs to walk 7,500 steps divided by 10 hours = 750 steps per hour.
On a number line, the solution can be represented by marking the starting point at 2,500 steps and then dividing the remaining 7,500 steps equally into 10 parts. The distance between each mark would represent the 750 steps she needs to get each hour for the rest of the day.
