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
Answer:
Price of senior citizen ticket = $7
Price of student ticket = $5
Step-by-step explanation:
<u>Let</u>:
- senior citizen ticket price = a
- student ticket price = b
<u>Equations formed</u> :
- 9a + 10b = 113
- 2a + 10b = 64
<u>Subtract</u> : Equation 1 - Equation 2
- 9a + 10b - 2a - 10b = 113 - 64
- 7a = 49
- a = 7
<u>Finding b</u>
- 2(7) + 10b = 64
- 10b = 50
- b = 5
<u>Solution</u>
- Price of senior citizen ticket = $7
- Price of student ticket = $5
