Question

Two trains leave the same station, each 40 minutes apart. Train X leaves first at 9:45 am and heads west at a speed of 144 km/h. Train Y leaves at noon and travels directly east at a speed of 165 km/h. How far apart are these trains at 1:30 pm? Show your work.

Answer 1

9:45 to 1:30 is 3.75 hours times 144 = 540 km

noon to 1:30 = 1.5 hours times 165 =247.5 km

247.5 + 540 = 787.5 km apart at 1:30 pm
