Answer:
Both trains are traveling at 90 miles per hour.
Step-by-step explanation:
We are told that the rate is the same for both trains, and we know that the distance traveled by train a plus the distance traveled by train b equals 585 miles.
We will use formula to solve this problem.
Train A: (Using 2.5 instead of 2 and 1/2)
Train B:
We can set an equation to solve for rate R of trains as:
Therefore, rate of both train a and train b is 90 miles per hour.
The graph shown below can be described using the equation y=Acos(bx)=k. Which of the following is the value of B +K.
