If it takes leaping Louie five minutes to jump three blocks how long will it take for him to jump 15 blocks?

15 = 3*5

so it will take 5*5 = 25 minutes.

As a proportion,
x/15 = 5/3

To find out how long it will take for leaping Louie to jump 15 blocks, we can use a proportion to compare the time it takes to jump 3 blocks and the time it takes to jump 15 blocks.

Let's set up the proportion:

Time to jump 3 blocks / Time to jump 15 blocks = 5 minutes / x minutes

Cross-multiplying, we get:

(Time to jump 3 blocks) * (x minutes) = (Time to jump 15 blocks) * (5 minutes)

Now we can plug in the values we know:

(3 blocks) * (x minutes) = (15 blocks) * (5 minutes)

Simplifying the equation:

3x = 75

Dividing both sides by 3:

x = 25

Therefore, it will take leaping Louie 25 minutes to jump 15 blocks.
