James loves to go swimming and has to swim across a 20-mile lake.  He can swim at a pace of 2 miles per hour.  He swims 60% of the distance.  After that, he stops on an island and rests for half as long as the swimming time.  He then finishes the remaining distance while going half the speed.  How long did it take him to get across the lake?
Jasmine o ne a na le distikara di le 15 - distikara di le 7 = <<15-7=8>>8 morago ga go latlhegelwa ke di le 7.
Morago ga moo, jaanong o na le distikara di le 8 + distikara di le 5 = <<8+5=13>>13 kwa bofelong.

He swam 20*.6=<<20*.6=12>>12 miles.
That took him 12/2=<<12/2=6>>6 hours.
So he rested 6/2=<<6/2=3>>3 hours.
He then swam the remaining 20-12=<<20-12=8>>8 miles.
His pace was 2/2=<<2/2=1>>1 mph.
So it took him 8/1=<<8/1=8>>8 hours.
So in total, he took 6+3+8=<<6+3+8=17>>17 hours.
