Question

If I went to the shopping mall at 3:05 pm and came back at 7:45.
How many hours and minutes was I gone?

Answer 1

Answer : 4 hours 40 minutes or 280 minutes

Step-by-step explanation:

There are 60 minutes in an hours so 1 hour = 60 minutes

3:05 to 4:05 = 1 hour

4:05 to 5:05 = 1 hour

5:05 to 6:05 = 1 hour

6:05 to 7:05 = 1 hour

7:05 to 7:45 = 40 minutes

1 hour + 1 hour + 1 hour + 1 hour + 40 minutes = 4 hours 40 minutes

Answer 2

Answer:

Check the explanation

Step-by-step explanation:

Given,

1st time = 3:05 pm

2nd time = 7:45 (am/pm)

To find,

The differences of time the second and first time.

Now,

CASE 1 ( 7:45 pm) :-

(we subtract here because both have the same unit pm)

Thus, differences of time = 7:45 pm - 3:05 pm

= 4 hrs 40 min

(:we subtract hour and min separately)

CASE 2 (7:45 am) :-

PLS mark me as brainliest if it really helped you !!!

(we add here because both have different units am and pm)

Thus, differences of time = 7:45 am + 3:45 pm

= 10 hrs 30 min

(:we add hour and min separately but since sum of min exceeds 60 min, we increase hour by 1 hour)
