In a group of nine people, one person knows exactly two others, two people know exactly 5 others, and another 2 people know exac

Rus_ich [418]

Answer:

1, 2 and 5 all know each other.

Step-by-step explanation:

I will denote the people by numbers: 1 2 3 4 5 6 7 8 9

The following information is given in the question.

1 knows two others

2 knows five others

3 knows five others

4 knows six others

5 knows six others

Let's assume the worst case: They all know different persons, so it is difficult to find three people who all know each other.

1 knows 2 and 5

2 knows 1 3 4 5 6

3 knows 9 8 7 6 2

By now, 2, 5 and 6 are known to two people, and others are known to just one person.

4 knows 9 8 7 6 5 3

5 knows 1 2 4 7 8 9

As a result 1, 2 and 5 all know each other.

1 knows 2 and 5

2 knows 1 and 5

5 knows 1 and 2

The reason for this is that there are three groups:

1, (2,3) and (4,5)

As much as we try to separate the people that they know there are nine different persons and at least three of them will be spread to these groups in common.

Daniel and Morgan both live 132 miles away from the beach it took Daniel 253 minutes less than two times the time it took Morgan

kenny6666 [7]

Answer:

It took 187.4 minutes to arrive Daniel at the beach.

Step-by-step explanation:

Given:

Daniel and Morgan both live 132 miles away from the beach it took Daniel 253 minutes less than two times the time it took Morgan to reach the beach.

Morgan drove at 36 mph.

Now, to find the time it take Daniel to arrive at the beach.

Let the time taken by Morgan be $x.$

And the time taken by Daniel is $2x-253.$

Distance = 132 miles.

Speed = 36 mph.

Now, to get the time taken by Morgan by putting the formula:

Distance = Speed × time

$132=36\times x$

Dividing both sides by 36 we get:

$3.67=x\\x=3.67\ hours.$

So, the time taken by morgan = 3.67 hours.

Thus, we convert the time into minutes:

$3.67\times 60\\=220.2\ minutes.$

Now, the time taken by Daniel, we get by substituting the value of $x$ :

$2x-253\\=2\times 220.2-253\\=440.4-253\\=187.4\ minutes.$

Therefore, it took 187.4 minutes to arrive Daniel at the beach.
