Worked Solution
Step 1: Find each student's total steps per day average summed across 3 months.
Ahmad: 6000 + 6500 + 7000 = 19 500 (thousands of day-steps)
Siti: 8000 + 7500 + 7000 = 22 500
Priya: 5000 + 6000 + 7000 = 18 000
Ravi: 7200 + 7200 + 7200 = 21 600
Step 2: Multiply each by 30 (days per month) to get total steps.
Ahmad: 19 500 x 30 = 585 000 steps
Siti: 22 500 x 30 = 675 000 steps
Priya: 18 000 x 30 = 540 000 steps
Ravi: 21 600 x 30 = 648 000 steps
Step 3: Compare. 675 000 is the greatest.
Answer: Siti walked the greatest total number of steps.
Correct answer: Siti
