What did Valli find out about the bus journey? How did she find out these details?

Explanation

Valli found out that the town was six miles from her village. The fare was thirty paise one way. The trip to the town took forty-five minutes. On reaching the town, if she stayed in her seat and paid another thirty paise, she could return home on the same bus. She found out these details by listening carefully to the conversations between her neighbours and the people who regularly used the bus. She also gained information by asking them a few questions.
