Sophia practiced for 5 hours and 20 minutes in total.
<u>SOLUTION:
</u>
Given that, Sophia practiced her flute the following times last week: 1 hr. 12 min., 57 min., 1 hr.
5 min., 30 min., 1 hr. 25 min., and 20 min.
We have to find how many hours and minutes did Sophia practice in all?
We just need to add them up all, but before that, let us convert them into minutes and later we can convert it into hours and minutes.
Then, 1 hr. 12 min ⇒ 60+12 = 72 minutes
57 min ⇒ 57 minutes
1 hr. 5 min ⇒ 60 + 5= 65 minutes
30 min ⇒ 30 minutes
1 hr. 25 min ⇒ 60 + 25 = 85 minutes and 20 min ⇒ 20 minutes.
Now, total time =72 + 57 + 65 + 30 + 85 + 20 = 329 minutes
Total time = 300 minutes + 20 minutes = 5 x 60 minutes + 20 minutes = 5 hours 20 minutes.
Hence, Sophia practiced for 5 hours and 20 minutes in total.
