Responder:

El remolque del tractor no atropellará a la vaca.

Explicación:

Dado lo siguiente:

Velocidad del tractor remolque: 69 km / h

Tiempo necesario para detenerse después de aplicar los frenos = 4 segundos

Distancia de vacas desde el remolque del tractor = 25 metros

Por lo tanto, la distancia recorrida por el remolque del tractor después de aplicar los frenos:

Velocidad del tractor remolque / Tiempo

69 km / h = (69 * 1000) m / 3600s = 69000m / 3600s = 19.17m / s

(19,17 m / s ÷ 4 s) = 4,8 m

Como la distancia de la vaca está más lejos (25 m), el remolque del tractor no pasará por encima de las vacas

If you divide a number into 3 equal groups and then divide each group in half, you end up with 13. The starting number is.
Vlad [161]

Answer:

The starting number is 78.

Explanation:

(x / 3) / 2 = 13

divide a number by 3 (x / 3)

divide in half (x / 3) / 2

You get 13 (x / 3) / 2 = 13

Reverse the problem.

13 * 2 = 26

26 * 3 = 78

x = 78

Plug in the number.

(78 / 3) / 2 = 13

78 / 3 = 26

26 / 2 = 13
