i need this for my homewotk

since the average of the 5 flight is 2 : 28

the total time was 5(2:28)
= 10:140
= 12:20

first 4 flights:
2 : 10
3 : 20
1 : 15
2 : 40
------
8 : 85 = 9 : 25

last leg = 12:20 - 9:25
= 2 : 55

Too bad the world can't can convert to "metric time"
It would make things soooo much easier.

Convert hours to minutes. Add all 4 known flights to get 565 minutes. Solve for "x".....565+x divided by 5 equals 148 minutes...148 x 5 = 740. 740-565=175 minutes...eqyals 2 hours 45 minutes (convert back to gours/minutes).
