The total flying time for two flights is 6 hours. The flight time for the first flight is half of the second. How long is each flight?
I need an expression :)

First flight= 2, second = 4

Step-by-step explanation:

Let's say the first flight = F and the second flight = S

If the first flight is half of the second, then S = 2F

F + S = 6

That means

F + 2F = 6

3F = 6

F = 6/3

F = 2

If the first flight equals 2 hours, and it is half of the second, then S = 2F, which is 4.

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.

hope my answer has you!
