It's no use worrying. Your question is incomplete. How do you answer them?

Hehe, your topic may be:

The distance between Station A and bilibili is 365 kilometers. A local train runs from Station A to bilibili at a speed of 65 kilometers per hour. After the local train runs 1h, the express train goes from bilibili to Station A with an hourly journey of 85km. How long does it take for the express train to meet the local train?

If this is the topic, you can do this:

(365-65* 1)/(65+85)

=300/ 150

=2 (hours)
