spayn [35]

Given:

Scott can run 20 km in 85 minutes.

To find:

How long will it take Scott to run 52 km?

Solution:

Let x be the number of minutes it will take him to run 52 km.

We know that,

Speed=\dfrac{Distance}{Time}

Using this formula, we get

Speed=\dfrac{20}{85}           ...(i)

Speed=\dfrac{52}{x}             ...(ii)

Equating (i) and (ii), we get

\dfrac{20}{85}=\dfrac{52}{x}

20\times x=52\times 85

20x=4420

Divide both sides by 20.

x=\dfrac{4420}{20}

x=221

Therefore, it will take 221 minutes to run 52 km.

If p and q are both true, then which of the following statements has the same truth-value as ~p → q?
olganol [36]

If p and q are both true, then

\neg p \implies q

is an implication of the form

F \implies T

which is true, because every implication starting with false is true, i.e.

F \implies T = T,\quad F \implies F = T

So, we're looking for an expression evaluating to true. Let's see what we have:

A) is an AND proposition. Logical AND is true only if both parts are true. So, you have

\neg P \land \neg Q = F \land F = F

So it's not the right option.

B) is an OR proposition. Logical OR is true whenever one of the two parts is true. So, you have

\neg P \lor\neg Q = F \lor F = F

So it's not the right option.

C) is again an AND proposition. You have

P \land \neg Q = T \land F = F

So this is not the right option.

D) Finally, the last one is again an implication, and again it starts with false:

\neg Q \implies P = F \implies T = T

So this is true, and thus is the correct option.
