Okay guys ...
here is the simple explanation (we should ALL get into the pearly gates now)

it is as simple as this ...
A chart ;;;
Train A leaves at 12 noon... Train B leaves at 12:30pm
at 1 pm- it has gone 50 miles
at 2 pm it has gone 100 miles
at 3 pm it has gone 150

Okay guys ...
here is the simple explanation (we should ALL get into the pearly gates now)

it is as simple as this ...
A chart ::::
Train A leaves at 12 noon...
at 1 pm- it has gone 50 miles
at 2 pm it has gone 100 miles
at 3 pm it has gone 150

Train B leaves at 12:30pm
at 1:30 pm it has gone 60 miles
at 2:30 pm it has gone 120 miles
at 3:00 pm it has gone 150 miles

my daughter figured this out

therefore they meet at 3:00 PM ....

My logic was...
total distance between cities is 225 miles. Train A will make that trip in 4.5 hours (225/50). Train B will make that trip in 3.75 hours (225/60). If train B leaves 30 minutes later (or .5 hours) and the difference in travel times is .75 hours, then they'll meet somewhere close to the middle.

If you want the exact answer, yes the math can be worked out for a precise time and distance. but I, too, thought it was probably a trick question about a city between those two places (like Hartford, CT) which someone who travels that trip would know.

(this was my friends answer)
