Effectively Jock gets 1km further every round of 1:10 hrs. After 8 rounds he has reached 8km (after just having floated back from 9 to 8). The next round he completes the journey without floating.
So total 9 hours of swim and 8*10 minutes of float, that's 10 hours and 20 minutes.
It is 3 but it is different a little bit because you need to move the y to the other side
Add the given fractions by finding the common denominator.
The common denominator of 3 and 4 is 12.
1/4 = 3/12
1/3 = 4/12
Now you can add them together: 3/12 + 4/12 = 7/12
Now subtract that from 1 to find the rest of the budget:
1 - 7/12 = 5/12
5/12 is left.
