A scientist uses a submarine to study ocean life.
She begins at sea level, which is an elevation of 0 feet.
She descends for 94 seconds at a speed of 3.3 feet per second.
She then ascends for 32 seconds at a speed of 1 feet per second.

At this point, what is her elevation, in feet?

Respuesta :

Answer:

[tex]278.2 \: ft[/tex]

Step-by-step explanation:

Descended feet:

[tex]94 \: s \times 3.3 \: \frac{ft}{s} \: = 310.2 \: ft [/tex]

Ascended feet:

[tex]32 \: s \times 1 \: \frac{ft}{s} = 32 \: ft[/tex]

Total elevation:

[tex](310.2 - 32) \: ft = 278.2 \: ft[/tex]
