Question

Suppose a dog can run 52 feet in 8 seconds. A cat can run 32 feet in 4 seconds. Which animal can run faster? How much faster?

Answer 1

The speed of a dog is `"6.5 ft/s"`.

The speed of a cat is `"8 s"`.

The cat can run 1.2 times faster.

Explanation:

`"speed"="distance"/"time"`

Speed of a dog

`"speed"=("52 ft")/("8 s")="6.5 ft/s"`

Speed of a cat

`"speed"=("32 ft")/("4 s")="8 ft/s"`

The cat can run faster.

`8/6.5=1.2`

The cat can run 1.2 times faster than the dog.
