Question 1191441
<br>
The times are the same; the difference in distance of the two trains is 330-280=50 miles, and the difference in their speeds is 25 mph.  That means the number of hours each train travels is 50/25=2.<br>
Train a traveling 280 miles in 2 hours means its speed is 140mph; train b traveling 330 miles in 2 hours means its speed is 165mph.<br>
ANSWERS (mathematically -- but not realistically): train a 140mph; train b 165mph<br>
