Casey has 5/6 left of a section of sidewalk to clean. If he can clean 5/18 of a section in 1 minute, how long will it take him t
GaryK [48]

Answer:

Casey will take 3 minutes to clean \frac{5}{6} part of the section.

Step-by-step explanation:

∵ Casey takes the time to cleans \frac{5}{18} of a section = 1 minute

∴ He will take the time to clean complete section = \frac{1}{\frac{5}{18} }

                                                                                  = 1\times \frac{18}{5}

                                                                                   = 3.6 minutes

Now time taken to clean \frac{5}{6} part of the section = \frac{5}{6}\times 3.6

                                                                            = 3 minutes

Therefore, left part of the section will be cleaned by Casey in 3 minutes.
