How did Valli plan her bus ride? What did she find out about the bus, and how did she save up the fare?

Valli planned that she would take the one o’clock afternoon bus, reach the town at one forty-five, and be back home by about two forty-five. She 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 had carefully saved whatever stray coins came her way, resisting every temptation to buy peppermints, toys, balloons, and the like, and finally she had saved sixty paise.
