Marjam has a goal of taking at least 10,000 steps today. According to her pedometer, she got 2,500 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? (1 point)
Marjam's goal is to take at least 10,000 steps today. She has already taken 2,500 steps in the morning. To find out how many more steps she needs to reach her goal:
Total steps needed = 10,000 steps
Steps taken so far = 2,500 steps
Steps remaining = Total steps needed - Steps taken so far
Steps remaining = 10,000 steps - 2,500 steps
Steps remaining = 7,500 steps
Now, there are 10 hours left in the day and she needs to split the remaining 7,500 steps equally across those hours. To find out how many steps she needs to take each hour:
Steps per hour = Steps remaining / Number of hours left
Steps per hour = 7,500 steps / 10 hours
Steps per hour = 750 steps
Marjam needs to walk 750 steps each hour for the next 10 hours to meet her goal of 10,000 steps.
To communicate this solution clearly in a graph, a bar graph or a line graph could be used.
A bar graph would have the hours on the x-axis and the number of steps on the y-axis, with each bar representing an hour and its corresponding steps.
A line graph would also have the hours on the x-axis and the number of steps on the y-axis, with a point for each hour showing cumulative steps. It would start at 2,500 steps at the beginning of the graph (representing the morning steps) and finish at 10,000 steps at the end of the graph, showing a straight line if the steps per hour are constant.
The line graph might provide the clearest communication of her progress towards her goal over time, showing each hour as a step towards the 10,000-step target.
