Debbie solved the linear equation 3(x + 4) - 2 = 16 as follows:
[Line 1] 3(x+4) - 2 =16
[Line 2]3(x+4)= 18
[Line 3]3x + 4 = 18
(Line 4]3x = 14
[Line 5] x = 4 2/3
She made an error between lines
A. 1 and 2
B. 2 and 3
C. 3 and 4
D. 4 and 5

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

idk what the heck he answer is, i’m just putting this here so i finish my account
