Aplane left atlanta at 4: 15pm and arrived at boston in 3hrs and 50mins. when did it arrive in boston?

4:15 pm, so 4 hrs and 15 minutes.

3 hours later will just be 3+4 hours or 7 hours and 15 minutes.

then if we add the 50 minutes to the 15 we get, 15 + 50 or 65 minutes, so that'd be 7 hours and 65 minutes.

since 60 minutes is 1 hour, then 65 minutes is just 1 hr and 5 minutes.

so 7 hours and 65 minutes is really 7 + 1  and 5 minutes, 8 hours and 5 minutes.

8:05.
