Between two rational numbers there are an infinite number of irrational numbers.
Example:
Let's assume time taken by plane on one way distance as 't'
The total flying time in both directions was 10.5 hr
so, time taken in other direction =10.5-t
now, we are given
A plane averaged 500 mph on a trip going east
so, total distance of one way is
total distance of other way is
now, we can that distance is same from both sides
so, we get
now, we can solve for t
now, we can find one way distance
