Answer:
The best could describe Anita's race from minute 3 to minute 5, She was standing, not moving, she could have been in an accident.
Step-by-step explanation:
See the attached figure.
As shown in the figure, we can note that the distance from minute 3 to minute 5 is constant which is equal to the distance at minute 3.
So, the average distance from minute 3 to minute 5 will be zero and hence the speed of Anita will be zero
So, From minute 3 to minute 5, She was standing, not moving.
Note: speed of Anita from minute 3 to minute 5
= ( distance difference) / (time difference) = zero / (5-3) = 0/2 = 0
To describe the race from minute 3 to 5, analyze the graph paying attention to the x and y axis and the slope of the curve. A straight line suggests constant speed, an upward line implies acceleration, and a downward line denotes deceleration.
To describe Anita's race from minute 3 to minute 5, we need to analyze the provided graph which depicts the distance from the start as a function of time for both racers. In this case, we do not have the actual graph so it's important that when you are presented with a graph you pay attention to the
x and y axis
, which in this instance are time and distance. It's vital to also look at the slope of the curve during those minutes 3 to 5 for Anita. If it's a straight line, it means Anita was biking at a
constant speed
. If the line is going upward, Anita was accelerating, and if the line is going downward, she was decelerating. Without the graph itself, it's hard to provide a definitive answer. But the basic method of reading the graph will help you understand the function of time and distance in the context of a race.

C. 420 in2
D. 288 in2
Dan's stamp book has 2 pages with 4 rows of stamps on each page. Each row has 2 stamps. How many stamps are on these pages of Dan's stamp book?
His average speed is,
⇒ 200 miles/hour
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
A driver was able to travel 600 miles in 3 hour.
Hence, His average speed is,
⇒ Speed = Distance / Time
⇒ Speed = 600 / 2
⇒ Speed = 200 miles/hour
Thus, His average speed is,
⇒ 200 miles/hour

Answer:
Step-by-step explanation:
It's 200km/hr, because if you divide the distance by the time you get your speed. You can also use the distance over speed and time formula to get your answer.
