How do you read a transport timetable to find a journey's duration, plan a connection and its waiting time, and work out the average speed of the trip?

Interpret timetables for buses, trains and ferries, including calculating the duration of a journey and the average speed of a trip

A focused answer to the HSC Maths Standard 2 dot point on interpreting timetables. How to read a bus, train or ferry timetable, find a journey's duration by subtracting the departure from the arrival, plan a multi-leg trip with a connection and its waiting time, and find the average speed of a trip with distance over time, using worked Australian examples.

How are points located on Earth by latitude and longitude, and how is the angular distance between two points turned into a distance in kilometres and nautical miles?

Understand the relationship between distance, angular distance (degrees and minutes) and time, using latitude and longitude to locate points on Earth's surface, and the definition of a nautical mile as one minute of arc along a great circle

A focused answer to the HSC Maths Standard 2 dot point on position on Earth. How latitude (N/S) and longitude (E/W) locate a point, finding the difference in latitude or longitude between two places, angular distance along a meridian, and the nautical mile, where one minute of arc equals one nautical mile, turned into a distance in kilometres and nautical miles.

How do you find the time difference between two places from their UTC offsets, and find the local time you arrive after a long flight that crosses the International Date Line?

Determine the time difference between two places given their time zones or UTC offsets, and solve problems involving the International Date Line and the local time of arrival after a journey, allowing for the change of date when crossing the line

A focused answer to the HSC Maths Standard 2 dot point on local time and the International Date Line. Time difference between two places from their UTC offsets, which place is ahead, crossing the date line (subtract a day going east, add a day going west), and the local arrival time on a long flight from the flight duration and zone change, with worked Australian examples.

How do world time zones work as offsets from Coordinated Universal Time, and how do you find the local time in another city by adding to the east, subtracting to the west and allowing for daylight saving?

Understand and use Coordinated Universal Time (UTC) and the relationship between time zones around the world expressed as offsets from UTC, including the link between longitude and time, to calculate the local time in different locations

A focused answer to the HSC Maths Standard 2 dot point on time zones and Coordinated Universal Time. UTC offsets, finding local time to the east (add) or west (subtract), allowing for daylight saving, and the longitude-to-time link of 15 degrees per hour, with worked Australian examples that track whether the answer lands on the previous or next day.

How do you convert between units of time, read 12-hour and 24-hour time, and work out how long something lasts when it crosses noon or midnight?

Use units of time, convert between 12-hour and 24-hour time, and solve problems involving elapsed time and the addition and subtraction of time

A focused answer to the HSC Maths Standard 2 dot point on units of time and 24-hour time. Converting between seconds, minutes, hours and days, reading and writing 12-hour (am/pm) and 24-hour time, elapsed time across noon and midnight, and adding or subtracting a duration from a start time, with worked Australian examples.
