Given:
Nick has x toy race cars. This is one-third of what Bob has.
So, the number of Nick toys = one-third of what Bob has.

So, the answer will be:
Bob has (3x) toy race cars.
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:
Answer:
DeAngelo's rate for the last 1.5 hours of his run is 7 miles per hour.
