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

<em>175</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>25 = 5²</em>
<em>35 = 5×7</em>
<em>Lcm = multiply together each of the prime numbers with the highest power</em>
<em>Lcm(25 ; 35) = 5²×7 = 25×7 = 175</em>
<em>Good luck !</em>

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

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

So,

Thus, there are 2275 Capulets and 0 Montagues.
