# A diver can hold his breath for two minutes under water. After practicing for a week, he can hold his breath for 5% longer. How long will he be able to hold his breath after the first week of practice?

2.1 minutes

Explanation

First, calculate 5% of 2: $$(5/100) \times 2 = 0.1$$
Then, add this increase to the amount of time the diver could originally hold his breath:
2 + 0.1 = 2.1 minutes
