Respuesta :

15 minutes. 25/5 = 5

5×3 = 15

Time required to cut a [tex]25[/tex] foot log into [tex]5[/tex] sections is equal to [tex]12[/tex] minutes as per given condition.

What is time?

" Time is defined as the duration required to complete something. It is a measurable period with some definite or indefinite action."

According to the question,

Time required to cut a log [tex]=3[/tex] minutes

Length of a given log [tex]=25[/tex] foot

Length of each section to be cut [tex]= 5[/tex] foot

Number of section cut from given log [tex]= \frac{25}{5}[/tex]

                                                               [tex]=5[/tex] logs

As shown in the diagram,

Number of log Bob has to cut to get [tex]5[/tex] logs [tex]= 4[/tex]

Time required to get [tex]5[/tex] logs [tex]= 3\times 4[/tex]

                                              [tex]= 12[/tex] minutes

Hence, time required to cut a [tex]25[/tex] foot log into [tex]5[/tex] sections is equal to [tex]12[/tex] minutes as per given condition.
