Did you figure it out?

Solution:  The crocodile swims 4 – 2 = 2 meters per second faster than the swimmer. So, the crocodile gets 2 meters closer to the swimmer each second. It takes the swimmer 20 meters ÷ 2 meters per second = 10 seconds to reach the boat. In that time, the crocodile gets 10 seconds × 2 meters per second = 20 meters closer to the swimmer. Since they were 30 meters apart to begin with, the crocodile does not catch the swimmer.

 

 

 

 

 

 

 

 

Did you figure it out?

Solution:  From 8:03 pm to 7:33 am is 11½ hours. So, the fairy travels a total distance of 16 × 11½ = 16 × 11 + 16 × ½ = 176 + 8 = 184 miles.
