Dolphin 1 dove 200 feet underwater. dolphin 2 dove 30% farther. after dolphin 2 dove down, it ascended 25.50 feet and the descended 40.50feet. how far underwater is dolphin 2

230 feet

Step-by-step explanation: Divide 200/30 to find the percentage. 30% of 200 is 15. Add the percentage to 200. Subtract 215 - 25.50. Then add 40.50.

275ft

Step-by-step explanation: dolphin 2 dove 130% the distance of the first, which is 1.3 * 200ft = 260ft.

Then it went up 25.5ft and down 40.5ft

260 - 25.5 + 40.5 = 275ft
