Answer:
The answer is option 2.
Step-by-step explanation:
In the question, the independent variable is time and dependent is distance. As the time changes, the distance will also change it means the distance depends on time.
For example,

Let t = 1,


Let t = 5,


Therfore, as time increases, distance will also increase.
This is for A part A: It shows that the least amount is 37.5 minutes
It shows the most amount of time is 60 minutes
One thing it does not show is how many students where in the class.
ANSWER for the first one:
A=a+b/2*h
A= 4.5+9/2*6
A= 40.5 cm2
ANSWER for the second one:
9*3= 27
3*3= 9
9*3= 27
A= 63 cm2
Answer:
The answer is 50 hours
Step-by-step explanation:
4x = 200
Divide both sides by 4
x = 200 \div 4 = 50
so after 50 hours of walking, the men will be 200 miles apart.
