Latest time?

Answer 1

Hi Jojo,

 

Lets make a list of the time spent doing all those activities prior to getting to school:

 

                                                1/2 and hour to get dressed=30minutes

                                                               20 minutes to eat=20 minutes

1/6th of an hour (1/6x60 minutes) to ride your bike to school=10 minutes

 

If you add up all the time you need to complete these tasks before getting to school, you would need:

30 minutes + 20 minutes + 10 minutes= 60minutes

 

So if you want to get to school at 8am, you would need to wake up 60 minutes before 8am so that you could complete all of the tasks that you need to. Therefore, you would need to wake up at 7am. 

 

Ans: 7 am

 

Hope this helps
