Let the second train catch up after x hours
<span>Distance = speed X time </span>
<span>135x = 105 ( 2 + x) </span>
<span>135x = 210 + 105x </span>
<span>30x = 210 </span>
<span>x = 7 hours (after 2nd train has started ) </span>
<span>ANSWER 7 X 135 = 945 miles from the starting point </span>
<span>CHECK </span>
<span>7 X 135 = 945 miles </span>
<span>9 X 105 = 945 miles</span>
Answer:

Answer:
y = -2/5x + 9
Step-by-step explanation:

And you'll always want to add the y = at the beginning
