:
Set down a few facts.
:
Your clock indicates that you were gone for 3 hrs (4 to 7)
:
Your friends clock indicates that you stayed for 2 hr (7pm to 9pm)
:
Your total travel time; 3 - 2 = 1 hr. One way = 1/2 hr
:
When you arrived at your friends house, it would be 4:30 on your clock, and 7 Pm on your friend's clock
:
To set the correct time, put your clock ahead 2.5 hrs
