Question

Megan,namiko and Omar are standing in a straight line. Megan and Omar are 20 feet apart and namiko is 7 ft from Omar. What are the possible distances between namiko and Megan ?

Answer 1

the answer is 13 feet

Answer 2

The distance between Megan and Omar is 20 feet.

Namiko is 7 feet from Omar.

Now we have two possibilities here:

Case 1:

If Namiko is standing between Megan and Omar ( as shown in figure case 1).

Distance between Namiko and Megan= Distance between Megan and Omar - Distance between Namiko and Omar

So distance between Namiko and Megain = 20-7 =13 feet.

Case 2:

If Namiko is standing 7 feet after crossing Omar ( as shown in figure case 2)

Distance between Namiko and Megan= Distance between Megan and Omar + Distance between Namiko and Omar

Distance between Namiko and Megan= 20 + 7 =27 feet
