Dos motos, A y B, toman la salida en una carrera de 90 km. La moto A realiza el recorrido con una velocidad media inferior en 20
aleksandr82 [10.1K]

Answer:

motorcycle A: 180 km/h

motorcycle B: 200 km/h

Step-by-step explanation:

To solve this question we need to write a system of equations for A and B, using the equation:

distance = speed * time

The speed of A is 20 less than the speed of B, so:

speedA = speedB - 20

And the time A traveled is 3 minutes (0.05 hours) more than B's time, so:

timeA = timeB + 0.05

Then, using the distance equation, we have that:

distanceB = speedB * timeB

90 = speedB * timeB

distanceA = speedA * timeA

90 = (speedB - 20) * (timeB + 0.05)

90 = speedB * timeB + 0.05 * speedB - 20*timeB - 1

90 = 90 + 0.05 * speedB - 20*timeB - 1

20*timeB = 0.05 * speedB - 1

timeB = (speedB - 20)/400

using this timeB in the distance equation, we have:

90 = speedB * (speedB - 20)/400

90 * 400 = speedB^2 - 20*speedB

speedB^2 - 20*speedB - 36000 = 0

Solving this quadratic equation, we have speedB = 200 km/h

And the speedA is:

speedA = speedB - 20 = 200 - 20 = 180 km/h

Premises: If a person has insufficient vitamin K, there will be a prothrombin deficiency. Mr. Keene does not have a prothrombin
Jet001 [13]

Answer:

The conclusion is Mr. Keene has sufficient vitamin K.

Step-by-step explanation:

Consider the provided statement.

The law of detachment involves two quantities, one is hypothesis and another is conclusion.

In the provided statement hypotheses and conclusion is:

Hypotheses (P): Person has insufficient vitamin K

Conclusion (Q): There will be a prothrombin deficiency.

Here if a person has insufficient vitamin K that means there must be prothrombin deficiency, but if a person has prothrombin deficiency we can't say anything.

Now it is given that Mr. Keene does not have a prothrombin deficiency.

That means he has sufficient vitamin K

Hence, the conclusion is Mr. Keene has sufficient vitamin K.

The required diagram is shown in figure.
