Answer:
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.
Step-by-step 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.
