Answer:

Sabrina necesito 8 horas para llegar a su casa mientras que Diana necesito solo 3.4 horas.

Step-by-step explanation:

debemos resolver la siguientes equaciones:

A + B = 11.4

65A + 50B = 690

donde:

A = tiempo que le toma a Sabrina llegar a su casa

B = tiempo que le toma a Diana llegar a su casa

A = 11.4 - B

65 (11.4 - B) + 50B = 690

741 - 65B + 50B = 690

741 - 690 = 65B - 50B

51 = 15B

B = 51 / 15 = 3.4 horas

A = 11.4 - 3.4 = 8 horas

Musya8 [376]

Answer:

22.5 miles per hour

Step-by-step explanation:

<u>Given system of equations</u>

5(s-w)=900

4(s+w)=900

<u />

<u>Set equations equal to each other</u>

5(s-w)=4(s+w)

5s-5w=4s+4w

s-5w=4w

s=9w

<u>Solve for w using the substitution s=9w</u>

4(s+w)=900

4(9w+w)=900

4(10w)=900

40w=900

w=22.5

Therefore, the speed of the wind is 22.5 miles per hour
