Explanation:
When two variables are inversely proportional, their product is equal to a constant.
In this case,
We are given the fact that the "trip takes
Let's substitute these values into the equation:
So the total distance of the trip is
Let's find out how long it takes to travel this distance at
Therefore, the trip takes
