Question

With all the numbers celebrating the return of $0$, the sun began to rise in the new world as morning approached. Suddenly, Ted heard his mom’s voice “Wake up.. You are going to be late for school today..” What? When? How?"
Yeah, you guessed it right, it was a dream. Ted got ready for school, his bus arrived. His house is beside MG Road, which leads straight to school. His school is $19$ blocks forward from Forum mall and his house is $5$ blocks backward to Forum mall. What is the expression that will give the distance between Ted's house and his school?

• A. (19 + 5) blocks
• B. (19×5) blocks
• C. (19 - (-5)) blocks
• D. (19 ÷ 5) blocks

Answer 1

Answer: (A), (C)

The correct options are
A

(19 + 5) blocks

C

(19 - (-5)) blocks

Ted has to walk $5$ blocks from his house to reach Forum mall, and then more $19$ blocks to reach his school. So, in total, Ted walks $(19+5)$ blocks to reach school from his home.

Also, we can consider Forum mall to be $0$, so that the position of Ted's house with respect to Forum mall on the number line can be taken as $-5$. Similarly, school can be taken to be placed at position $19$. So, the distance between Ted's house and his school would be $19-(-5)$.
