2 trains leave the station. Train A leaves at 12:00 heading to a city 5,000 miles away going 156mi/h. And taind B leaves the station at 1:30 going 212mi/h heading to a town 4,353 miles away who will get there first arrive at there detestation first?
+130514 Using ... distance / rate = time, we have
The first train takes 5000/156 = about 32 hrs to reach its destination
The second takes 4353/ 212 = 20.5 hrs
Now....I'm assuming that the "12:00" is 13.5 hrs before the "1:30" or else it's clear that the second train will arrive first...so....using my assumption......
The first train will "win" because it takes 11.5 hrs longer to reach its destination, but since it started 13.5 hrs. sooner than the second train, it reaches its destination about two hours earlier.....
