This can be translated in two ways.
or
Either way, the only way that this could be equal to 0 is if x = 0.
Therefore the solution is x = 0.

Either way, the only way that this could be equal to 0 is if x = 0.
Therefore the solution is x = 0.
For this case, the first thing we must do is define a variable.
We have then:
p: rate in miles per hour for the last 1.5 hours
We now write the equation that models the problem.
We have then:
Rewriting we have:
From here, we clear the value of p.
We have then:
