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:
1/4^18
Step-by-step explanation:
We can simplify the equation by dividing 4^8 on the numerator and on the denominator.
Doing this, we get that 1/4^18 is the answer.
Answer:
30.667, in 1 hour = 40 miles
Step-by-step explanation:
Set up a proportion so 1.5 miles / 2.25 minutes.
So 1.5/2.25 = x/46
solve for x 1.5(46)/2.25 = x so x = 30.667
In one hour is 60 minutes so 1.5(60)/2.25 = x
Answer:
12
Step-by-step explanation:
I think you have to use the product rule for counting- which is where you multiply the two numbers. I'm not sure if this is right but I hope I helped
