Jackie starts work at 9: 30 am. in the morning she reads the newspaper for 17 minutes, showers and gets dressed in 25

minutes, and rides her bike to work in 20 minutes. what is the latest she can wake up and still be on time for work?

8: 28 AM is the latest Jackie can wake up and still be on time for her work.

Step-by-step explanation:

Time taken by Jackie to read paper =17 minutes

Time taken to get dressed and shower = 25 minutes

Time taken to ride to work = 20 minutes

So, the total time needed by Jackie to get ready = Time to get dressed + Time taken to read paper + Time to ride

= 17 minutes + 25 minutes + 20 minutes =

62 minutes  = 1 hour + 2 minutes

Now, the office time = 9: 30 AM

One hour before 9:30 AM is 8:30 AM

and two minutes before  8: 30 is  8:28 AM.

So, the time by which she has to get up to be on time  8: 28 AM which is 62 minutes earlier than 9:30 AM

Hence, 8 : 28 AM is the latest Jackie can wake up and still be on time for her work.
