Answer:
300 meters away
Step-by-step explanation:
it will take the dolphin 50 seconds to finish the race( 400/8 )
it will take the man 200 seconds to finish the race( 400/2 )
by the time the dolphin crosses the finish line it will take the swimmer 150 seconds to reach the finish line (200 - 50 seconds)
recall the swimmer swims at 2 meters per second and has 150seconds to reach the finish line hence he is 300 meters away ( 150 x 2)

Hi there! The answer is h = 65
To find our answer we plug in our data in the formula:
![4082 = 3.14 \times 10 \times 2 \times h](https://tex.z-dn.net/?f=4082%20%3D%203.14%20%5Ctimes%2010%20%5Ctimes%202%20%5Ctimes%20h)
![4082 = 20 \times 3.14 \times h](https://tex.z-dn.net/?f=4082%20%3D%2020%20%5Ctimes%203.14%20%5Ctimes%20h)
![4082 = 62.8h](https://tex.z-dn.net/?f=4082%20%3D%2062.8h)
Divide both sides by 62.8
