Answer: About 3.06
Step-by-step explanation:
We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.
Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.
cos(θ) =
cos(40) =
0.766 ≈
3.06 ≈ x
x ≈ 3.06
Answer:
The rate of car travel is 5.2 kilometers per minute.
Step-by-step explanation:
We are given the following in the question:
Total time of travel = 22 minutes
Total distance covered = 114.4 kilometers
We have to find the rate at which the car is travelling.
Formula:
Rate, r
where d is the distance covered and t is the time.
Putting values, we get,
Thus, the rate of car travel is 5.2 kilometers per minute.
