A cat is at -3. A rat is at number 10. Assuming both are standing on a number line, how far is the rat from the cat?
13 units
As per the question
A cat is at -3 on the number line.
A rat is at number 10 on the number line.
∴ The distance between them = 10 - (-3) = 10 + 3 = 13 units
Hence, the rat is 13 units away from the cat.
