A train leaves from Newcastle for Sydney at 7:45am, while another train leaves from Sydney to Newcastle at 8:15am. The first train arrives in Sydney 40 minutes after the trains pass, while the train to Newcastle arrives 1 hour 40 minutes after they pass. Assuming that the trains travel at different but constant speeds. Find the time the two trains passed each other.:eek:

You shouldn't double post.
