Question 455757: Please help me solve this word problem: The express train traveled at a speed that was three times as fast as the freight train. The express train traveled 630 miles in one hour less than it took the freight train to travel 360 miles. What were the speed and time for both the express train and the freight train?

630/3s+1=360/s
630+3s=1080
3s=450
s=150
3s=450
630/450+1=2.4
360/150=2.4
The freight train moved at 150 mph. The express train ran at 450 mph..
