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)

Answer 1

To determine how many steps Marjam needs to take each hour for the rest of the day to reach her goal of 10,000 steps, we can follow these steps:

1. Calculate the remaining steps needed:
   Marjam has already taken 2,500 steps.
   Steps needed to reach 10,000:
   \( 10,000 - 2,500 = 7,500 \) steps.

2. Determine the number of hours left:
   There are 10 hours left in the day.

3. Calculate the number of steps needed per hour:
   To find out how many steps she needs to take each hour, divide the remaining steps by the number of hours left:
   \( \frac{7,500 \text{ steps}}{10 \text{ hours}} = 750 \text{ steps per hour} \).

Thus, Marjam needs to walk 750 steps each hour for the remaining 10 hours to meet her goal of 10,000 steps.

Graph Communication

To communicate the solution clearly, a bar graph representing:

• Total steps (10,000)
• Steps she has taken (2,500)
• Steps needed (7,500) This would effectively show the relationship between the total goal and the progress she has made, highlighting what still needs to be achieved. The bar graph should also label the steps per hour for clarity.

If selecting a type of graph, a simple vertical bar graph showing the total goal versus the current progress and needed steps would be most effective in illustrating this solution.
