Description:

This lesson, part of a series of mathematics lessons that use spatial analysis as the framework and GIS as the toolkit, invites you to analyze problems involving travel. Objectives: Investigate travel and intersection problems by using travel time and distances within a GIS environment. 20 Questions. The classic travel scenario is an algebraic story problem and is a variation on the following theme: “City A and City B are 500 km apart. A train departs City A at 8:00am local time and travels toward City B at 100 kph. Another train departs City B at 9:00am and travels toward City A at 130 kph. At what time will the 2 trains pass each other? How far from City A and from City B will they pass (or “intersect”) each other?” The travel problem is an important one in mathematics, because several concepts can be taught and understood through it, such as algebra, measurement, calculations, units of measure, conversions, percentages, time, and distance. Within a GIS environment, the travel problem can be analyzed in the context of real places and distances on maps. Revised 21 May 2010.
