Well, Kate and Harry together are walking 100 meters per minute. Which means it will take them 25 minutes to reach each other (I think).
If the dog is running 120 meters per minute: 120 x 25 = 3,000.
The dog will run 3,000 meters (if he runs constantly to and from the spot that Kate and and Harry started).

Answer:
252
Step-by-step explanation:
The number of integers from 100 to 999 is 999 - 100 +1 = 900.
Consider the number of three-digit integers that <em>do not contain 4 </em>as a digit.
For the <em>hundreds</em> digit, there are 8 possible choices (excluding 0 and 4).
For the <em>tens digit</em>, there are 9 possible choices (excluding 4).
For the <em>ones</em> <em>digit,</em> there are 9 possible choices (excluding 4)
Thus, there are 8 × 9 × 9 = 648 three-digit integers without a 4.
The number of three-digit integers with at least one 4 is 900 - 648 = 252.
