Blizzard [7]

Answer: 60 miles

Step-by-step explanation:

Given

It takes ferry 2 hours to travel to town A and only 1.5\ hr to travel back to town B.

Speed of current is u=5\ mph

Suppose the speed of the ferry is v mph

Distance traveled in both the cases is same, but it took more time traveling to city A that is, ferry is moving upstream and downstream for returning time.

\Rightarrow 2(v-5)=1.5(v+5)\\\Rightarrow 2v-10=1.5v+7.5\\\Rightarrow 0.5v=17.5\\\Rightarrow v=35\ mph

Distance between the towns is 2\times (35-5)=60\ \text{miles}

Jori has 7 boxes of books,with each box holding the same number of books.he has126 books in all how many books are there per box
bazaltina [42]
Let b be the number of books in a box.  Then we can say that the total number of books is equal to the number of boxes times the number of books per box.

7b=126  divide both sides by 7

b=18

So there are 18 books per box.
