Question

Imagine that this graph represents the distance Brianna travels to get to her babysitting job with respect to time. Describe a relation that the graph may represent.

Answer 1

Answer:

The distance time graph shows the velocity with which Brianna traveled.

From t= 0 to t = 6:

For every 2 minutes, distance increase by one miles. She covers 3 miles in 6 minutes.

So the velocity is given by:

velocity = change of distance/ change of time

velocity = 3/6

velocity = 0.5 miles/minutes

From t=6 to t=10

As there is no change in distance, the velocity of the object is 0, it means Brianna is stationary from t=6 to t=10

From t=10 to t=16

Distance covered = 7 miles - 3 miles = 4 miles

Time taken = 16 - 10  = 6 minutes

Velocity = 0.67 miles/minutes

Answer 2

Answer:Brianna left home and drove 3 miles in 6 minutes. She then stopped for 4 minutes to pick up coffee. Finally, she traveled the last 4 miles in 6 minutes to arrive at her babysitting job.
