Lesson Summary:

In this lesson, we learn how to solve distance problems using the rt=d formula. We are given a word problem about a pilot flying from one city to another city and then back again, with different speeds for each direction. By setting up equations for rate, time, and distance, we're able to solve for the distance between the two cities, which is 300 miles. It's important to carefully read the question being asked and make sure to answer it correctly. With practice, we can become skilled at solving these types of problems.

Lesson Description:

Solves this word problem using rt=d formula: A pilot flew from one city to another city averaging 150 mph. Later, it flew back to the first city averaging 100 mph. The total flying time was 5 hours. How far apart are the cities?

This final installment of uniform motion problems. Again, a picture and a chart are used to write and solve an equation to find the solution to this problem. Once you do several of these problems, you will see that the process is very similar even though the wording of the problems, what you are given, and what you are trying to find is different in each one.
