Question

Ratios problem?

Answer 1

8:00 a.m.

Explanation:

Since the train is going at 50 mph for 3 hours, it has travelled 150 miles before the second train has started. The second train is going 10mph relative to the first train (60mph - 50mph), therefore when you divide `(150mi)/(10(mi)/(hr)`, you get 15 hours. That plus the 2:00 p.m. start time and the 3-hour delay between the trains gives you 8:00 a.m.
