Question

Where would Jack stand when he hops 3 units on a number line 3 times starting from 4?

• A. 5
• B. 13
• C. 10
• D. 4

Answer 1

The correct option is B 13

Hopping 3 times on number line means multiplying by 3.
Given that Jack is already at 4. So, we need start from 4 and then hop from 4 for 3 units for 3 times. That is add 4 with the product of 3 and 3.

$⟹4+(3\times 3)=4+9=13$
Therefore, Jack will be standing at 13.
