stacey has 3 lessons in the morning. lesson 1 starts at 8:55am. each lesson is 60 minutes long. there is a 20 minute braeak between lesson 2 and 3. what time does lesson 3 end?

The lesson 3 will end by 12:15 pm

Solution:

Given that, Stacey has 3 lessons in the morning.

We have to find what time does lesson 3 end?

Lesson 1 starts at 8:55 am

Each lesson is 60 minutes long

Then, lesson 1 ends by 8:55 + 60 minutes ⇒8:55 + 1:00 hour ⇒ 9:55 am

Now, the second lesson will end by ⇒ 9:55 + 60 minutes ⇒ 9:55 + 1:00 hour ⇒ 10:55 am.

there is a 20 minute break between lesson 2 and 3

Then, break will end by 10:55 + 20 minutes ⇒ 11:15 am.

Now, the third lesson will end by 11:15 am + 60 minutes ⇒ 11:15 + 1:00 hour ⇒ 12:15 pm

Hence, the 3rd lesson will end by 12:15 pm
