When Kenny's electricity went out one night, his clock stopped at 8:39 p.m. when Kenny woke up the next morning his power was back on and his clock read 5:34 a.m. When he called the time services, the time was actually 7:11 a.m. How long was his electricity off?

Respuesta :

Answer:

Step-by-step explanation:

Let's look at this in this perspective. There are 60 minutes in 1 hour. What I would do first is get rid of the 39 minutes at the end of 8:39. Now you have 8:00. Count until you get to 7 AM.  9, 10, 11, 12, 1, 2, 3, 4, 5, 6, 7. That's 11 hours from 8 PM to 7 AM.  60 x 11 = 660. Now, there are 11 minutes more on that 7-o clock and the 39 minutes we got rid of in the beginning. 11 + 39 = 40. 660 + 40 = 700.

Answer: Kenny's energy was off for 700 minutes, or 11 hours and 40 minutes.
