The amount of time it took him to run 3 miles at 6 mph is 30 minutes

If Kirk ran 10 mph for a full hour, he would travel 10 miles.  Since he only runs for half that, he would travel 5 miles

Answer:

5 miles.

Step-by-step explanation:

We have been given that for a set amount of time, the distance Kirk can run is directly related to his average speed. Kirk can run 3 miles while running 6 miles per hour. We are asked to find the distance covered if his speed increases 10 miles per hour in same time.

\text{\text{Time}}=\frac{\text{Distance}}{\text{Speed}}

\text{\text{Time}}=\frac{3\text{ Miles}}{\frac{\text{6 miles}}{\text{Hour}}}

\text{\text{Time}}=\frac{3\text{ Miles}}{\text{6 miles}}\times \text{Hour}

\text{\text{Time}}=0.5 \text{Hour}

Now, we need to find distance covered at a rate of 10 miles per hour in 0.5 hour.

\text{Distance}=\text{\text{Time}}\times \text{Speed}

\text{Distance}=\text{\text{0.5 hour}}\times \frac{\text{10 miles}}{\text{Hour}}

\text{Distance}=0.5\times \text{10 miles}

\text{Distance}=5\text{ miles}

Therefore, Kirk can run 5 miles in same amount of time at a rate of 10 miles per hour.

Five times the sum of the digits of a two-digit number is 13 less than the original number. If you reverse the digits in the two
mafiozo [28]

Answer:

The difference of the original two-digit number and the number with reversed digits is 18.

Step-by-step explanation:

Since it's a two digit number, let x represent the tens digit and let y represent the units digit.

Thus, the original two digit number is;

10x + y.

The reverse two digit number is;

10y + x.

We are told that five times the sum of the digits of the two-digit number is 13 less than the original number.

Thus;

5(x + y) = (10x + y) - 13

Multiplying out the bracket gives;

5x + 5y = 10x + y - 13

Rearranging gives;

10x - 5x + y - 5y = 13

5x - 4y = 13 - - - - (3)

Also,we are told that, four times the sum of its two digits is 21 less than the reversed two-digit number. Thus;

4(x + y) = (10y + x) - 21 - - - (4)

Simplifying gives;

4x + 4y = 10y + x - 21

>> 10y - 4y - 4x + x = 21

>> 6y - 3x = 21 - - - (4)

Solving eq(3) and (4) simultaneously gives;

x = 5 and y = 3

Thus,

Original number = 53

Reversed number = 35

Difference between original and reversed number = 53 - 35 = 18

Find the length of LK
ehidna [41]
Since JN = NK, this means that JK has been split into two equal pieces

This points to the fact that the smaller triangle is half of the larger triangle in terms of side lengths

MN = 14 which means LK is twice as long, so LK = 2*MN = 2*14 = 28 

In summary,

LK = 28
