Step-by-step explanation:
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
