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 |
does this make sense ... 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) |
:fainted: Thats what I would do if someone asked me this! |
