Question

Suppose three lamp posts exist on a straight

Answer 1

Answer:

324 ft

Step-by-step explanation:

1. We know there are 3 points (A, B, and C)

so far. We also know B is in the middle of A and C.

A----B----C

2. Reading further, post B is 2x as far from C as it is from A.

A----B----.----C

3. Now we know the numeral measurements of the entire stretch going from A to C (486ft).

A----B----.----C

<- 486ft ->

4. How far is point B from C??? Using the info we have, we need to break the total(486) into 3 parts.

A----B----.----C

1 2 3

5. When we divide or break 486 into 3, we get 162 ft. So each of those 3 dividing sections between A B and C are 162ft.

A----B----.----C

162 162 162

6. We know that the dividing section between B and C is double the dividing section between A and B. So, to conclude, you double 162 = 324.

7. Make sure to put it into the correct form to answer (ft) and there you go!
