Diego ect post number 3

From the beggining of the trip to the end was atleast one full week. But how long was it exactly? My plane was scheduled to leave at 6:20 a.m. on saturday, may 16, which ment we had to be at the airport at 4:30 a.m. My plane was scheduled to get back in at 11:50 p.m. the next saturday. So from 4:30 a.m. on one saturday to 11:50 p.m. on the next saturday was the length of our trip. If one day is 24 hours, then 7 days is 168 hours. From 4:30 a.m. on the first saturday to 4:30 a.m. on the second saturday was 168 hours. There is still some remaining hours though. From 4:30 a.m. to 11:50 p.m. is 19 hours. Now, 168 + 19 = 177 hours.
