use the drop-down menus to give the best estimates to the questions below.
running: 63 minutes
lifting: 18 minutes
gene spends about minutes running and lifting in 1 day.
gene will spend about minutes running and lifting in 5 days.

Explanation:

Step1: Estimate daily exercise time

First, we estimate the time for running and lifting. 63 minutes can be estimated as 60 minutes, and 18 minutes can be estimated as 20 minutes. Then we add them together: $60 + 20 = 80$ minutes.

Step2: Estimate 5 - day exercise time

We use the daily estimated time (80 minutes) and multiply it by 5: $80\times5 = 400$ minutes.

Answer:

Gene spends about 80 minutes running and lifting in 1 day.
Gene will spend about 400 minutes running and lifting in 5 days.
