Algebra-2

Let's assume the speed of Train 2 is  miles per hour. Then the speed of Train 1 is  miles per hour.

We'll use the formula , where  represents time,  represents distance, and  represents speed.

For Train 2, which travels a distance  miles at a speed of  miles per hour, the time taken  hours.

For Train 1, which travels a distance  miles at a speed of  miles per hour, the time taken  hours.

We are given that it takes Train 1  hours less to complete its route than Train 2. So we can set up the following equation:

To clear the fractions, we multiply through by :
