Question

Charlotte is starting a running plan to train for a race. In the first week of her running plan,

Charlotte will run 5 miles. The plan calls for Charlotte to increase her weekly mileage by 4 miles
every week. If Charlotte sticks to the plan, how many miles would she be expected to run during
her 11th week of the training plan?

Answer 1

Charlotte would be expected to run 45 miles during her 11th week of the training plan.

Step-by-step explanation:

To calculate the number of miles Charlotte would be expected to run during her 11th week of the training plan, we need to determine how many miles she will have increased her weekly mileage by during the previous 10 weeks.

Since Charlotte increases her weekly mileage by 4 miles every week, we can use the formula:

Weekly Mileage in Week N = Weekly Mileage in Week 1 + (Increment per Week * (N - 1))

Plugging in the values:

Weekly Mileage in Week 11 = 5 + (4 * (11 - 1)) = 5 + (4 * 10) = 5 + 40 = 45 miles
