Answer:
Total time = 19 minutes.
Explanation:
Given the following data;
Time to shower = 720 seconds
Time to eat breakfast = 420 seconds
To find the total time in minutes;
Total time = 720 + 420
Total time = 1140 seconds
We know that 60 seconds equals a minute.
Total time = 1140/60
Total time = 19 minutes.
Therefore, it will take Andrew 19 minutes to take a shower and eat breakfast.
