Answer:
2 miles per hour
Step-by-step explanation:
We have to calculate the miles per hour of each person
Formula = Distance in miles/ Time in hours
a) For Pepe
Pepe averaged a speed of 4/5 of a mile in 1/10 of an hour
Hence,
= 4/5 miles / 1/10 hour
= 4/5 miles ÷ 1/10 hour
= 4/5 miles × 10/1 hour
= 8 miles per hour
b) For Paula
Paula averaged 5/6 of a mile in 1/12 of an hour.
Hence,
= 5/6 miles / 1/12 hour
= 5/6 miles ÷ 1/12 hour
= 5/6 miles × 12 hour
= 10 miles per hour
Therefore, In miles per hour, the number of miles Paula ran faster than Pepe is calculated as:
10 miles per hour - 8 miles per hour
= 2 miles per hour
Y = 11 x + 1
11 x + 12 y = 12
----------------------
11 x + 12 * ( 11 x + 1 ) = 12
11 x + 132 x + 12 = 12
143 x + 12 - 12 = 12 - 12
143 x = 0
x = 0
y = 11 * 0 + 1
y = 0 + 1
Answer:
y = 1
The probability is p = 2/5, the correct option is the third one.

How to find the probability?</h3>
There is a total of 6 socks, such that 4 are black and 2 are blue.
Then the probability of first getting a black sock is the quotient between the number of black socks and the number of blue socks, which gives:
P = 4/6
Now there are 5 socks in total, such that 3 are black and 2 blue.
Then the probability of getting another black one is:
Q = 3/5
The joint probability (getting the two black socks) is given by the product of the individual probabilities:
p = (4/6)*(3/5) = 2/5
The correct option is the third one.
