Ahorizontal line on a distance time graph represents

We can say that a horizontal line on a distance time graph represents the object is not changing its position, it is at rest or not moving.

Step-by-step explanation:

Consider the provided information.

Distance time graph help us to identify the distance cover by the object with time.

Where x axis represents the time and y axis represents the distance as shown in figure below:

From the graph we can see that there is a horizontal line.

This lines shows that time is increasing from left to right but distance is same.

It means object is not changing its position or we can say that the object is at rest or not moving.

Hence, we can say that a horizontal line on a distance time graph represents the object is not changing its position, it is at rest or not moving.

answer: do you still need this?

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
