welll...you have there written just one relationship...it is berween 280 and 4 hours...you have to figure out speed:

it is speed per hour
then you just connect time and speed:
- 140 - 2
- 280 - 4

- 420 - 6
- 560 - 8
- 700 - 10

Answer:

Step-by-step explanation:
We want to model the position of the submarine as a function of time.
Notice that we have a constant amount. The initial depth: 750 meters
Then we have a factor that varies over time. Every hour the submarine ascends 50 meters. therefore as t increases the depth y(t) of the submarine decreases. Then the factor is:
-50t.
Where t represents the time in hours.
Then the equation that represents the new position of the submarine in relation to the level of the sea:
