Yuto and Lian are at train stations 1,880 kilometers apart. Yuto boards a train heading east at an average speed of 220 kilomete
rs 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?
<span>Then distance traveled by Yuto to meeting point = 1,880 - D
Times taken by both to travel to meeting point are equal
Therefore, we get: 1880 - D/220 = D/250
250(1,880 – D) = 220D ------ Cross-multiplying
470,000 – 250D = 220D
- 250D – 220D = - 470,000
- 470D = - 470,000
D, or distance Lian traveled = -470000/-470, or 1000 km </span>
to calculate area its pie * diameter with the diameter in this question being 1.5 and when it says to the nearest hundredth it means to the second away from the point
