3 Distance is proportional to time.

4 Not much information.

Explanation:

We are required to match the options to whether distance is proportional to time in the following situations.

1. A horse running around a race track.

Since, the horse is running around the race track. So, the speed of the horse can vary at different time

So, distance is not proportional to time.

2. A truck passing through 4 cities at a constant speed.

As, Distance = Speed × Time and we are given that the speed is constant.

So, distance is directly proportional to the time.

3. A dog jogging at a constant speed for 20 minutes.

As, Distance = Speed × Time and we are given that the speed is constant.

So, distance is directly proportional to the time.

4. A person running down a field to score a touchdown.

Since, there is no information about the speed of the person.

But, as the person is running to score a touchdown, he may run at a constant speed.

So, there is not much information.

Hence, we have,

Situation Relation

1 Distance is not proportional to time.

2 Distance is proportional to time.

3 Distance is proportional to time.

4 Not much information.
