The second train finally caught up with the first train after traveling for three hours. One train left the station and traveled toward its destination at 65 mph.

Later, another train left the station traveling in the opposite direction of the first train at 75 mph.

You will also apply the formula that solves distance, rate, and time, which is There are many examples where you might use this formula in real life.

For example, if you know the time and rate a person is traveling on a train, you can quickly calculate how far he traveled.

This can be done by first multiplying the entire problem by the common denominator and then solving the resulting equation. Click Here for Practice Problems Example 4 – One roofer can put a new roof on a house three times faster than another. How long would it take the faster roofer working alone?

This can be done by first multiplying the entire problem by the common denominator and then solving the resulting equation. Click Here for Practice Problems Example 5 – Triplets, Justin, Jason, and Jacob are working on a school project.

Organize the information you have in a chart format if you haven't solved these types of problems before.

Remember the formula: When identifying the parts of the word problem, distance is typically given in units of miles, meters, kilometers, or inches.

You are usually told how long each person takes to paint a similarly-sized house, and you are asked how long it will take the two of them to paint the house when they work together.

Many of these problems are not terribly realistic — since when can two laser printers work together on printing one report?
