Answer:
Train 1: 368 mph
Train 2: 358.1 mph
Step-by-step explanation:
We can write 2 equations to represent this problem.
The x represents the first train and the y represents the second train.
We can plug in x into the first equation.
Now that we know our y, we can find our x.
The answer is
C
2
Answer: 194
1. Square both sides to get (b+2)=14^2=196
2. Subtract 2 from both sides to get b=194
