Question

Maria's house is shown by a yellow circle and Martin's house is shown by a red circle in the figure given below containing a number line. How many steps and in which direction Maria needs to move to reach Martin's house?

• A. $6$ steps towards left
• B. $6$ steps towards right
• C. $9$ steps towards left
• D. $9$ steps towards right

Answer 1

The correct option is D $9$ steps towards right

Initially, Maria is at $-3$. She needs to reach Martin's house, which is situated at $6$.


So, to reach Martin's house at $+6$, Maria needs to move $\underset{–}{9}$ steps towards the right from $-3$ as illustrated below.


$\therefore$ (d.) is the correct option.
