Answer:
The correct option is B.
Step-by-step explanation:
Solution:
The shortest on map is 7cm
The longest on map is 14 cm
The shortest in real life is 120 km
Let the longest in real life is x km
So,
The ratio is:
7/120 = 14/x
x = 120*(14) / 7
x=1,680/7
x= 240 km
The longest in real-life is 240 km
Thus the correct option is B....
If three points were A, B and C are collinear points and B is between A and C, then AB+BC=AC

The average rate of change for a function over an interval is the slope
<h3>How to explain the steps?</h3>
Take for instance, we have the function to be
Function f(x)
And the interval is (a,b)
The average rate of change for the function over the interval is
Rate = (f(b) - f(a))/(b - a)
The above represents the slope
Take for instance, we have:
f(x) = x^2 [2, 4]
We have:
f(2) = 2^2 = 4
f(4) = 4^2 = 16
So, we have:
Rate = (16 - 4)/(4 - 2)
Rate = 6
