Answer:

Step-by-step explanation:
Let third cook take x hours to prepare the same number of pies y alone
Let y be the number of pies
In 1 hour ,third cook prepare pies=
One experienced cook takes time to prepare enough pies =4 hours
In 1 hour , cook prepare pies=
Another cook takes time to prepare same number of pies =7 hours
In 1 hour , another cook prepare pies=
All three cooks take time to prepare the same number of pies=2 hours
In 1 hour,all three cooks prepare pies=
According to question





hours
Hence, the third cook takes time to prepare the same number of pies alone=
These are the steps, with their explanations and conclusions:
1) Draw two triangles: ΔRSP and ΔQSP.
2) Since PS is perpendicular to the segment RQ, ∠ RSP and ∠ QSP are equal to 90° (congruent).
3) Since S is the midpoint of the segment RQ, the two segments RS and SQ are congruent.
4) The segment SP is common to both ΔRSP and Δ QSP.
5) You have shown that the two triangles have two pair of equal sides and their angles included also equal, which is the postulate SAS: triangles are congruent if any pair of corresponding sides and their included angles are equal in both triangles.
Then, now you conclude that, since the two triangles are congruent, every pair of corresponding sides are congruent, and so the segments RP and PQ are congruent, which means that the distance from P to R is the same distance from P to Q, i.e. P is equidistant from points R and Q
