Ian is looking to lose some weight. He decides to start jogging around his apartment complex every night to burn some calories. He does 5 laps around the complex every night. Each lap is 100 feet. If it takes 25 feet of jogging to burn a calorie, how many calories does Ian burn after 5 days of jogging like this? Let's be accurate as possible.
First, we need to determine how many feet Ian runs in a week. We begin this by multiplying the number of laps by the number of feet per lap, performing 5 * 100 = 500 feet per day. Since there are 5 days in the period being measured, this means Ian runs 500 * 5 = 2500 feet jogged. Since it takes 25 feet of jogging to burn a calorie, this means Ian burns 2500 / 25 = 100 calories burned jogging throughout the week.
The answer: 100.
