Question

Bobby's cat runs x mph. Bobby's dog runs twice as fast as his cat. If cat and dog start running away from each other how far away from each other will they be after 30 minutes?

Answer 1

1.5x

Explanation:

Answer 2

Let's start by finding the speed of the dog:

Dog's speed = 2 * Cat's speed

Dog's speed = 2x mph

To find how far away they will be after 30 minutes, we need to first find the distance each one travels in that time.

Distance = Speed * Time

Cat's distance = x * 0.5 = 0.5x miles

(30 minutes = 0.5 hours)

Dog's distance = 2x * 0.5 = x miles

Now we can find the total distance between them:

Total distance = Cat's distance + Dog's distance

Total distance = 0.5x + x

Total distance = 1.5x miles

So after 30 minutes, the cat and dog will be 1.5x miles away from each other.
