If a train goes 50 mph and gets somwhere in 10 minutes and another train goes 100 mph and gets somwhere in 5 minutes if they both left at the same time would they both get to the same place at the same time?
(this is not any homework so don't ask)

Insufficient information. It depends on the trains' starting positions and their direction of travel.
Even if the trains start in the same place and travel on the same track, you can come up with conditions under which the answer is "yes". For example, the trains could be going on a circular track, in which case both trains could end up in the same place at the same time. One has just lapped the other, that's all.
If both trains are starting in the same place and going in the same direction on a straight track, then the only time they'll be at the same place is at the moment when they start traveling. However, the problem doesn't specify that this is the case, and a good mathematician wouldn't go around assuming so.

distance =velocity*time
Train 1 d= 50/60*10= 8.333 miles
Train 2 d=100/60*5= 8.333 miles. They get to the same place but not at the same time.Train 2 arrives 5 min before train 1

ok distnace = velocity * time
so in case one d = 50*10=500 m
in case 2 d= 100*5=500m
but the question is did they left same PLACE at same TIME heading same DIRECTION
if yes they will reach together
but why would two trains do that smem time same place same direction was they goinig the final of world cup chapmpionship and there were thousands of audience or what ..............

No, they wouldn't, because train 2 is traveling at twice the speed so he would get there sooner; 5 minutes sooner to be exact.

no they wouldn't
if neither train stopped, the only place they would be at the same time is the starting point

If they leave at the same place, follow parallel tracks, and arrive at the same place, then they will arrive at the same time.

No, the second train is travelling twice as fast.

they can if the one that went 100mph slows down 50 or if the one that went 50mph speeds up 50. other than that they'll remain 5min apart

Simplistic answer; no
Realistic answer; It would depend on how rapidly they accelerated to their respective speeds.
