Uniform Motion Problems |
---|
Uniform Motion Problems are problems where an object moves at a uniform speed. These problems are solved used weighted averages. |
Imagine you have to drive to a friend’s house that is 60 miles away. There is heavy traffic on the way there, so your entire trip takes 2 hours. On the way back traffic is light, and your trip only takes 1 hour. What was your average speed for the entire trip?
To:
60 = rate * (2)
30 = rate
From:
60 = rate * (1)
60 = rate
To find the average speed for the entire trip, we take a weighted average:
