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 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?

Question

A. Marjam's Steps per Hour for the Remainder of the Day
there is a number line going from 0 to 10 and there is a dot in between 8 and 9
B. Marjam's Steps per Hour for the Remainder of the Day
there is a number line going from 0 to 900 and there is a dot on 750
C. Marjam's Steps per Hour for the Remainder of the Day
there is a number line going from 0 to 900 and there is a dot on 750
D. Marjam's Steps for the Remainder of the Day
there is a number line going from 0 to 900 and there is a dot on 750

Answer 1

The correct graph is B. Marjam's Steps per Hour for the Remainder of the Day, with a dot on 750.

To calculate the number of steps Marjam needs to take each hour for the rest of the day, first subtract the steps she has already taken from her goal:
10,000 - 2,500 = 7,500 steps remaining

Since there are 10 hours left in the day, divide the remaining steps by the number of hours:
7,500 / 10 = 750 steps per hour

Therefore, Marjam needs to take 750 steps each hour for the rest of the day in order to meet her goal of 10,000 steps.
