This is a free lesson from our course in Algebra I
This lesson deals with other word problem formats, such as time-distance problems, and explains them with the help
of several solved examples. Typically, in time-distance problems, you need to use
the idea of rate or speed. Speed is simply distance over time, i.e.
speed = distance / time. Conversely, distance can be calculated multiplying speed and time. For example, if a passanger
traveled for 4 hrs at 30 miles per hour, then the total distance covered will be
120 miles.

(Continued from above) "Distance-Time" word problems, involve something travelling at some fixed and steady ("uniform") pace ("rate" or "speed"), or else moving at some average speed. Whenever you read a problem that involves "how fast", "how far", or "for how long", you should think of the distance equation, d= s*t, where d stands for distance, s stands for the (constant or average) rate of speed, and t stands for time.
As many of you know, Winpossible's online courses use a unique teaching method where
an instructor explains the concepts in any given area to you in his/her own voice
and handwriting, just like you see your teacher explain things to you on a blackboard
in your classroom. This particular lesson includes the teacher's instruction, practice
questions as well as end-of-lesson quizzes for practice. As we mentioned above,

The format of Winpossible's online courses is also very suitable for teachers who
are using an interactive whiteboard such as Smartboard on Promethean in their classrooms,
because the course lessons can be easily displayed on such interactive whiteboards.
