Solving Linear Word Problems

The second train is going 85 mph for t time, or 85t. In other words, when do the two distances add up to the total distance, 800 miles. Now, we divide both sides by 160, and we get t = 5.

The first train is traveling at a rate of 75 mph, so the distance it covers in t time is 75t.

In these equations, we're trying to figure out the variable, which involves getting it alone on one side of the equals sign.

There are simple problems that involve linear equations.
