Answer:
960 km
Step-by-step explanation:
Speed = Distance/Time.
From the question, we are to find the Distance.
The formula for Distance is given as:
Speed × Time.
From the question:
Speed = 960 km/hr
Time = 1 hour
Distance = 960 km/hr × 1 hour
Distance = 960 km
Therefore, the airplane can travel for 960km in 1 hour

Answer:
False, 5 is not a factor of 54.
We will see that the solution in the given interval is: x = 0.349 radians.
<h3>How to solve equations with the variable in the argument of a cosine?</h3>
We want to solve:
cos(3*x) = 1/2
Here we must use the inverse cosine function, Acos(x). Remember that:
cos(Acos(x)) = Acos(cos(x)) = x.
If we apply that in both sides, we get:
Acos( cos(3x) ) = Acos(1/2)
3*x = Acos(1/2)
x = Acos(1/2)/3 = 0.349
So x is equal to 0.349 radians, which belongs to the given interval.
