Step-by-step explanation:
Jason starts riding a bike 1 mile from the station.
Shawn starts biking 2 miles from the station.
For Jason to reach Shawn, he needs to go at a higher speed. However we know that they are going at the same constant speed. Then they will never meet.
To prove it we propose the following system of equations. Where x is the hours and y is the distance in miles.
For Jason we have:

For Shawn
.
We want to know when Jason and Shawn are at the same distance.
Then we write the following eqution and clear x:

Equality is not satisfied. Therefore, it has no solution.
I mean Jason and Shawn will never be the same distance
