Question

Peter opens his shop at 9:30 qm and closes it at 8:00 pm. How long is his shop open?

Answer 1

Answer:

His shop opens for 10:30 hours

Answer 2

Answer:

Here is the answer....

Step-by-step explanation:

Given,

Opening time of Peter's Shop =  9.30

After adding 1 hour = 10.30

Adding 1 hour again = 11.30

Adding 1 hour again = 12.30

Adding 1 hour again = 1.30

After adding repeatedly for ten times (including what we added before it becomes 7.30)

Adding 30 minutes it becomes 8 pm.

Therefore,

The shop is open for 10 hours and 30 minutes.

Hope this helps..
