1. Dos automóviles Ay B hacen un mismo trayecto de 572 km. El automóvil A lleva recorridos los 5/11 del trayecto cuando el B ha recorrido los 8/13 del mismo. ¿cuál de los dos va primero? ¿cuantos kilómetros lleva recorrido cada uno?

Respuesta :

Answer:

1. El auto B comenzó primero

2. El automóvil A recorrió una distancia de 260 km, mientras que el automóvil B recorrió una distancia de 352 km

Step-by-step explanation:

This question is in Spanish. Let’s have an English translation;

Two cars A and B make the same 572 km journey. Car A has traveled 5/11 of the journey when B has traveled 8/13 of it. Which of the two goes first? How many kilometers has each traveled?

Let’s now proceed to solve the question.

To answer this question properly, we have to assume that both cars are covering the same distance at the same speed but they started at different times. So, let’s now proceed;

The first question is another way of asking which of both is a bigger fraction.

Now Car A travelled 5/11 and Car B had traveled 8/13, to know which of both that started first, the one that subtracts the other without leaving a negative answer started first.

Let’s say Car B - Car A = 8/13 - 5/11 = 34/143

This obviously means that Car B went first.

Second question asks to calculate how many kilometers has each traveled. We calculate this by finding the fraction of the journey multiplied by the distance traveled by both.

For Car A, we have 5/11 * 572 = 260km

For Car B, we have 8/13 * 572 = 352km
