Answer:

13 minutes

Step-by-step explanation:

∵ Joe runs 8 miles in the time = 1 hour or 60 minutes

∴ Joe runs 1 mile in the time = \frac{60}{8} minutes

∴ Joe runs 13 miles in the time = \frac{60\times 13}{8} minutes

                                                   = 97.5 minutes

∵ Marjorie runs 8 miles in the time = 52 minutes

∴ Marjorie runs 1 miles in the time = \frac{52}{8}

∴ Marjorie runs 8 miles in the time = \frac{52\times 13}{8}

                                                         = 84.5 minutes

Therefore, times taken less by Marjorie to complete the marathon = 97.5 - 84.5 = 13 minutes.

VashaNatasha [74]

<em>The question has inconsistent or incomplete data, so I'm filling the holes with key data.</em>

Answer:

<em>Every people at dinner received one-tenth of the original turkey= 0.1</em>

Step-by-step explanation:

<u>Proportions</u>

If some fraction a/b of a whole total M is to be computed and later removed, we proceed as follows

* Compute the portion to be removed as a/b*M

* Subtract it from the total quantity: M-a/b*M=M(1-a/b)

I'm assuming 1/5 of the turkey was lost due to overcooking. It means that (1-1/5) of the turkey remained for dinner, that is, 4/5 of the turkey.

Each people at dinner received the same amount of the remaining, so we must divide 4/5 by 8, to get 4/40, or 1/10. It means that every people at dinner received one-tenth of the original turkey

186x = 1116
x = 1116 : 186
x = 6 tickets (answer).
