Question

Andy wakes up at 6:45 a.m. Before leaving for school, he takes 15 minutes to get dressed in 30 minutes to eat breakfast. What time does he leave for school?

Answer 1

You need to analyze the information given in the exercise.

You know that he wakes up at 6:45 a.m. So notice that you can divide this time in hours and minutes. This would be: 6 hours and 45 minutes.

Since he takes 15 minutes to get dressed, you need to add 15 minutes to the 45 minutes shown above:

$45\min +15\min =60\min$

You need to remember that 60 minutes is 1 hour. This means that 6 hours and 45 minutes plus 15 minutes is:

$7\colon00\text{ }a.m.$

Now you have 7 hours and 0 minutes. So, if you add 30 minutes (the time he takes ti eat his breakfast):

$7\colon30\text{ }a.m.$

The answer is:

$7\colon30\text{ }a.m.$
