The solution to Problem 6
Below (after the reminder) is the solution to the Problem 6 of the lesson Some logic problems (the topic Miscellaneous word problems
of the section Word problems in this site).
Problem 6 formulation (reminder)
Bev takes a train home at 4:00 pm, arriving at the station at 6:00 pm. Every day, driving at the same rate, her husband meets her at the station.
One day, she takes the train an hour early and arrives at 5:00 pm. Her husband leaves home to meet her at the usual time, so Bev begins to walk home.
He meets her on the way and they arrive home 20 min earlier than usual. How many minutes did Bev walk?
Solution
Since the husband returned home with Bev 20 minutes earlier than usual, he spent 10 minutes less time in each direction than usual.
It means that the husband met Bev not at 6:00 pm at the station as usual, but he met her walking from the station at 5:50 pm.
Hence, Bev was walking from 5:00 pm till 5:50 pm, i.e. 50 minutes.
Answer
How many minutes did Bev walk? - 50 minutes. From 5:00 pm till 5:50 pm.
