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:
5,000 m
Step-by-step explanation:
One KM is equal to 1,000 m.
5 KM = 5,000 m.
First, subtract 10.2 from 8.5
8.5 - 10.2 = -1.7
Next, add -7.4 to -1.7
-7.4 (+) - 1.7 = -9.1
Your final answer is -9.1
