Un bus avanza con MRU a 72 km/h. Determinar el tiempo que le toma
avanzar 200 m.

El tiempo que le toma al bus con movimiento rectilíneo uniforme MRU avanzar 200 m es:  t= 10 seg

Para determinar el valor del tiempo que le toma al bus con movimiento rectilíneo uniforme MRU avanzar 200 m se procede a aplicar las fórmulas respectivas a dicho movimiento, como se muestra a continuación:

V = 72 Km/h = 20 m/seg

t =?

 d = 200 m

  Fórmula del movimiento rectilíneo uniforme MRU :

    V = d/t

 Se despeja el tiempo t :

     t = d/V

     t = 200m / 20 m/seg

     t= 10 seg

step-by-step explanation:

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
