Short answer: Yes
The two hypotheses are
1. f(x) is continuous on the interval [0, 2].
This hypothesis is satisfied. A polynomial function is continuous everywhere.
2. f(x) is differentiable on the interval (0, 2).
This hypothesis is satisied. A polynomial function is differentiable everywhere.

Answer:
V = 5 m/h
Step-by-step explanation:
An aircraft carrier, traveled 9 hours at speed of 25 mph, that means the aircraft position from Hawaii (the start point of the journey) is:
25 m/h * 9 h = 225 miles far away from hawaii
When the aircraft has traveled 9 hours, the submarine has traveled 11 hours ( since its departure was 2 hours earlier ). They both traveled in opposite directions.
Then distance between the two vessels = d
d = 280 miles
280 = 225 miles (from the aircraft to hawaii ) + traveled distance for the submarine
And
Traveled distance by submarine d(s) = V* 11 miles/hour. where V is speed of submarine
Then
280 = 225 + 11*V ⇒ 11*V = 280-225 ⇒ 11*V = 55/11 mph
V = 5 m/h
