### Final assignment

**How the Learning Object Works**

Choose a station to START.

Choose a station to END.

Choose a date on the calendar by using the green buttons.

Input the time needed to travel for HOURS and MINUTES.

Click on GO AHEAD to proceed.

Data is shown.

To start over, click on CHANGE STATIONS.

Repeat step (1).

**For Decision-making**

The commuter of the West Rail can use it for planning his/her journey. In the social context, there can be a number of uses for different scenarios:

Commuter A is late for work. He needs to decide whether to take the bus or the West Rail to travel from Tuen Mun to Tsuen Wan. So he checks up on the expected arrival time of the next train and the travel time needed to arrive at his destination to decide on which mode of transport to take.

Commuter B is on a day off from work. She wants to travel from Mei Foo to Tin Shui Wai to visit the Wetland Park with her family. They also want to avoid the rush hour traffic. So she looks at the train frequency to decide on the earliest time when the rush hour is over.

**For Mathematics Teaching and Learning**

The idea is to introduce some mathematical and other concepts for primary and secondary students. For instance:

The further the distance between 2 stations, the longer it takes to travel (proportionality).

Different times of the day will have different train frequencies arriving on platforms (business concepts).

Time it takes to travel from A to B (speed).

The whole journey from A to B starting from when commuter arrives on the platform, including the time required to wait for the next train.
