When the two trains pass each other, the total distance traveled by both Yuto and Lian is 1,880 kilometers.
Using the formula distance = rate x time for both Yuto and Lian, we get:
220t + 250t = 1,880
470t = 1,880
t = 4 hours
Therefore, Lian has traveled 250 x 4 = 1,000 kilometers when the two trains pass each other.
Yuto and Lian are at train stations 1,880 kilometers apart. Yuto boards a train heading east at an average speed of 220 kilometers per hour. At the same time, Lian boards a train heading west on a parallel track at an average speed of 250 kilometers per hour. How far has Lian traveled when the two trains pass each other?
