Question

A train leaves Boston at noon going to NYC at a speed of 60 mph. Two hours later, an express train leaves NYC going to Boston at a speed of 90 mph. At what time will they meet if the distance between the two stations is 240 miles?​

Answer 1

Train A: Speed of 60 mph. (1 mile per minute)

Train B: Speed of 90 mph. (1.5 miles per minute)

after 2 hours: (2:00)

Train A has gone 120 miles. (half-way mark)

Train B has gone 0 miles.

Hour 2:48: (2:48)

Train A has gone 168 miles.

Train B has gone 72 miles.

72 ----><---------------168

At 2:48 P.M the two will meet. 72+168=240

I hope this helps! :)
