a train leaves a station and travels north at a speed of 105mph. two hours later, a second train leaves on a parallel track and
travels north at 135mph. how far from the station will they meet
1 answer:
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:
21.2
Step-by-step explanation:
N is an odd integer
The Next Larger is N+2
N+2 + 2N = -27 + 4N
3N + 2 = 4N - 27
0 = 4N - 27 - 3N - 2
0 = N - 29
N = 29
They are 29 and 31.
31 + 2(29) = 4(29) - 27
31 + 58 = 89 = 116 - 27 yes it works
