Chapter 1.3, Problem 47WE

To determine

To find: the number of points on $\overrightarrow{AB}$ , that the distance from point B is more than $3\text{ cm}\text{.}$

Answer to Problem 47WE

There exist one or two points on $\overrightarrow{AB}$ .

Explanation of Solution

Given information:

On $\overrightarrow{AB}$ consider $3\text{ cm}$ distance.

Calculation:

Consider the below figure.

The distance between A and B is more than $3\text{ cm}\text{.}$

So, they are two points from point B is $3\text{ cm}\text{.}$

Hence, they are one or two points on the line $\overrightarrow{AB}$ .
