Train A and B are traveling in the same direction on parallel tracks. Train A is traveling at 100 miles per hour and train B is traveling at 120 miles per hour. Train A passes a station at 10.10 A.M. If train B oases the same station at 10:25 A.M., at what time will train B catch up to train A?
time is only an illusion of relative motion
does it say anything about the two trains' starting at the same position, or anything like that?
no thats all the info
At the time train B catches up with train A, they would have traveled same distance from station except it would have taken Train B 15 min less time to get there. **Note: 15 min = 0.25 hr d = r*t 120(t-.25) = 100t 120t - 30 = 100t 20t = 30 t = 1.5 It took 1.5 hrs from time Train A passed station for train B to catch up, or at 11:40
