Use t as target time length if the train were on-time. There are two speed conditions:

Speed__________________Time hours______________distance miles
40______________________________________
30______________________________________

The distance expressions in the table were both somewhat simplified, and based on . These distances are EQUAL, being between two given but unspecified same towns. We form this equation:

Solve for t, the target time, and then use it to compute distance between the towns, using either distance expression.
