Answer:
1. 1.5 inches per minute
2. 90 inches per hour
Step-by-step explanation:
speed = 
1. total distance covered =
+ 
= 
= 
= 4
inches
Total time taken =
+ 
= 
= 
= 3 minutes
The ants average speed = 
= 1
= 1.5
The ants speed is 1
inches per minute.
2. Since;
60 minutes = 1 hour
3 minutes = x hours
x = 
= 
= 0.05 hours
Speed = 
= 90 inches per hour
The red ants speed is 90 inches per hour.
Answer:
The slope is 2
Step-by-step explanation:
Slope formula:
m=(y2-y1)/(x2-x1)
Given:
y2 = -10
y1 = -6
x2 = 2
x1 = 4
Work:
m=(y2-y1)/(x2-x1)
m=(-10 + 6)/(2 - 4)
m= (-4)/(-2)
m = 2

Answer:
Average rate of change = 2
Step-by-step explanation:
Formula to get the rate of change of a function between x = b and x = a is,
Rate of change = 
We have to calculate the average rate of change between x = -2 and x = 0
From the graph attached,
At x = -2,
f(-2) = 0
At x = 0,
f(0) = 4
Therefore, average rate of change = 
=
= 2
Average rate of change of the given function between x = -2 and x = 0 is 2.
