The rainstorm flooded the wetlands and washed Phineas Frog 200 yards away from his home in the swamp.  To return home, he will need to hop and swim his way back.  If he hops on land at a speed of 20 yards per minute, and swims through water at a speed of 10 yards per minute, how long will it take Phineas, in minutes, to return home if half of the distance is on land and the other half is in water?

Half of 200 yards is 200/2=<<200/2=100>>100 yards.
100 yards at 20 yards per minute is 100/20=<<100/20=5>>5 minutes.
100 yards at 10 yards per minute is 100/10=<<100/10=10>>10 minutes.
In total, it will take Phineas 5+10=<<5+10=15>>15 minutes to return home.
