Answer:
Directly
Explanation:
Let's look at this closely
165 km = 1.5 hours.
That is what is given to us by the problem,
now let's assume that the problem is asking how many km it will get in 2 hours if the train spends 2 hours. It must mean that the train is gonna get more distance than 165 km because it has more time.
So to sum it all up
If the hours go up, that means the distance will be farther.
Directly is when if one quantity goes up, the other quantity goes up, but the inverse is when if one quantity goes up, then the other quantity goes down.
In this case, the hours go up, and the distance is farther which means it's going up.
To conclude, your answer is direct,
