Answer:
50
Step-by-step explanation:
.3x=15
x=50
Formula: Distance = rate * time
570 = (R+(R-18))*3
570 = (2R - 18)*3
190 = 2R-16
208 = 2R
R = 104
Eastbound Train: 86mph
Westbound Train: 104mph
You can do
83 - 5 to find the answer
So that's
78 or
5 + 78 = 83
Whenever it says divide just flip the fraction and change it to multiply
