Answer: 60mph
Step-by-step explanation:
500-300 = 200
200 = distance traveled in 2 hrs
100 = distance traveled every hour
100=2x+20, x being the slower train
80=2x
x=40
40+20 = 60, the speed of the faster train

Answer:
y=mx+b broken down is in the step by step explanation.
Step-by-step explanation:
y=mx+b is the y intercept formula.it is mostly used for slopes.
y is usually equal to the total,or final answer.it is the start.
m is equal to the slope.in the formula.it can also be used as the rise over run,which means the top number is the amount of units you go up for rise,and run is the bottom number which is the amount of units you move to the right.if it is negative,you move the opposite ways.if it is a single number,the bottom number can be 1.
x is equal to the number you multiply m,or the slope by.
b is equal to where you start on the vertical line in the graph.a way to remember it is horizontal is like a horizon,it’s flat.
