Question

Ronnie can paint 8 rocks in 5 minutes. How long will it take him to paint 54 rocks

Answer 1

33 minutes and 45 seconds.

Explanation:

We can easily set up a proportion...

He can paint 8 rocks in 5 minutes. He can paint 54 rocks in x minutes.

`(8)/(5) =(54)/(x)`

8 * x = 54 * 5

8x = 270

4x = 135

x = 33.75

So, it will take Ronnie 33 minutes and 45 seconds to paint 54 rocks.

Hope this helps!

Answer 2

8 rock in 5 minutes

54 rocks / 8 rocks = 6.75

6.75 x 5 minutes = 33.75 minutes
