If you just start thinking about 1hour the passengers will go 60miles and the freight 40m so it makes sense that the freight needs 30 more min to catch up right ? so in 3 hours the passengers will go 180 miles... the freight will then be at 120 and will need 3x30min to catch up right ? I'm gona go with 3hours and 4.5hours

velocity times time is distance, and the distances are equal, so we can set the following expressions equal\[v_1t_1=v_2t_2\]\[60(t-1.5)=40t\]solve for t. One time will be t and the other will be t-1.5.
