A sea turtle descends 28 feet from the surface of the ocean and then ascends 5 feet. Then it descends 9 feet and repeats this descent 4 times. How many feet below the surface is the turtle then ?

Respuesta :

Parrain

Answer: 59 feet

Step-by-step explanation:

First the sea turtle descended 28 feet.

It then ascends 5 feet which means it is now:

= 28 - 5

= 23 feet below surface

It then descends 9 feet and repeats that descent 4 time:

= 9 * 4

= 36 feet below the surface

Total distance below the surface:

= 23 + 36

= 59 feet
