Zachary travels on a journey of 50 miles. He spends half
ExtremeBDS [4]

Answer: 8 hours.

Step-by-step explanation:

We have the relation:

Time  = distance/velocity

Distance = 50 miles

Velocity in horse = 9mph

Velocity walking = 3 1/2 mph = 3.5 mph

Then, if T is the total time, X is the distance that he travels in horse and Y is the distance that he travels by foot, we have:

X + Y = 50 miles:

T/2 = X/9mph

T/2 = Y/3.5mph

Then we have:

X/9mph = Y/3.5mph

X = Y*(9/3.5)

And by the first relation:

X = 50 mi - Y

then we have:

50mi - Y = Y*(9/3.5)

50mi = Y + Y*(9/3.5) = Y*(1 + 9/3.5) = Y*3.57

Y = 50mi/3.57 = 14mi

Then we have:

T/2 = 14mi/3.5mph

T = 2*(14/3.5) hours = 8 hours

makvit [3.9K]

Answer: The answer is 2275 and 0.


Step-by-step explanation:  Given that the Capulet and Montague families love to write. Last year, each Capulet wrote 44 essays, each Montague wrote 66 essays and both families wrote 100100 essays in total. This year, each Capulet wrote 88 essays, each Montague wrote 1212 essays, and both families wrote 200200 essays in total. We are to find the number of Capulets members and Montagues members.

Let there are 'x' members in Capulet family and 'y' members in the Montague family. Then, we have

44x+66y=100100,\\\\88x+1212y=200200.

Multiplying first equation by 2 and then subtracting from the second equation, we have

1212y-132y=200200-200200\\\\\Rightarrow 1080y=0\\\\\Rightarrow y=0.

So,

x=\dfrac{100100}{44}=2275.

Thus, there are 2275 Capulets and 0 Montagues.
