The correct option regarding the error in calculating the length of segment AB is given as follows:
There should have been a subtraction instead of an addition, and the correct length is of 3.5 units.
<h3>Where are points A and B?</h3>
Researching the problem on the internet, it is found that points A and B are on a number line, with coordinates given as follows:
<h3>What is the length of the segment?</h3>
The length of the segment is the absolute value of the subtraction of the endpoints, hence:
L = |4.5 - 1| = |1 - 4.5| = 3.5.
The error is that:
There should have been a subtraction instead of an addition, and the correct length is of 3.5 units.

Answer:
0.3 hour or 18 minutes
Step-by-step explanation:
How long means, we are to calculate the time(t)
Hence,
Speed × time = Distance
For Neil , 11 × t
For Charlie = 9 × t
11t + 9t = 6
20t = 6
t = 6/20
t = 0.3 hour
Converting to minutes
1 hour = 60 minutes
0.3 hour = x
x = 0.3 × 60 minutes
x = 18 minutes
Therefore, it will take 0.3 hour or 18 minutes for these two to meet.
