Ben decides to prepare for a marathon by running ten minutes a day, six days a week. Each week, he increases his time running by three (3) minutes per day. How many minutes will he run in week 8?

Sagot :

Answer:

To determine how many minutes Ben will run per day in week 8, we can follow these steps:

1. Identify the initial time Ben runs per day in week 1: 10 minutes.

2. Calculate the weekly increase in running time: 3 minutes per day.

3. Determine the total increase in running time by week 8: \((8 - 1) \times 3\) minutes per day.

4. Add the total increase to the initial running time to find the running time in week 8.

Here are the calculations:

1. Initial running time per day: 10 minutes.

2. Weekly increase: 3 minutes per day.

3. Number of weeks to increase: \(8 - 1 = 7\) weeks.

4. Total increase in running time: \(7 \times 3 = 21\) minutes.

5. Running time per day in week 8: \(10 + 21 = 31\) minutes.

Therefore, Ben will run 31 minutes per day in week 8.
