4 laps = 6 minutes
8 laps = 12 minutes
Only half the laps being done would mean the minutes taken to swim the laps would also be half meaning 6/2 = 3. 12+3=15
10 laps = 15 minutes.

14 minutes. Because f you put them in fraction for it would be

4/6 --> 10/x

Solve for X

10 devided by 4 = 2.5

6 x 2.5 = 14

So x = 14 minutes
