This is a question Question of the Week suggestions

Each week we ask a question. The idea is to generate material that's:

* interesting to read, i.e. we won't get bored of reading the answers after about 10 of them
* not been asked on this site before
* fun to answer

What would you like to ask? (We've left this question open - so feel free to drop in ideas anytime.)

Boston and New York are approximately 280 miles apart.
One Train leaves Boston traveling towards New York at an average speed of 80mph. Another train leaves New York at the same time traveling toward Boston at an average speed of 60 mph. (a) How long will it take them to meet? (b) How far has each train traveled when they meet?

When did this happen?
Speeds on the NECR have increased and the introduction of Acela stock has reduced passing time considerably.

Could you specify traction, time of day and payload? Also sectional timings would help.

Also, what's the curvature of the line?

Also, it requires knowledge of the distance - by rail - between Boston and New York
which is almost certainly more than the straight line distance, a number you also fail to provide. This is a very poor question.

When it says 'toward', is this by the shortest route?
Because you could, you know, go around the world in the opposite direction to get to it.

Using the new worldwide aquarail system.

Strictly the shortest route, of course, would be by tunnelling through the earth. This feat of engineering may have to wait until the first lava-proof trains are developed, though.

I hear this is actually a real plan.
