A dog runs towards a person down the street for 30 meters. The dog reaches them in b seconds. How fast was the dog running?

A) 30 meters per second
B) 30/b meters per second
C) 30/b meters per minute
D) 30/b meters per hour

Answer 1

The speed at which the dog was running is 30/b meters per second.

Step-by-step explanation:

To calculate the speed at which the dog was running, we can use the formula:

Speed = Distance / Time

In this case, the distance the dog ran is 30 meters and the time it took is b seconds. Therefore, the speed will be:

Speed = 30 meters / b seconds = 30/b meters per second

So, the correct answer is B) 30/b meters per second.
