You have the formula already, just plug in 30 for s (speed) and solve for d (distance).
The equation given in the question should be written down first and then the process should start for solving and finding the value of the unknown variable "x".
6x + 8 = 2x + 11
6x - 2x = 11 - 8
4x = 3
x = 3/4
The value of the unknown variable "x" comes out to be 3/4. I hope the procedure for solving this equation is clear enough for you to understand. In future you can always use this procedure to get to the solution of similar problems.
