5х + 6 = 5х = 4
what type of solution is this

I believe this is a False solution

Step-by-step explanation: when you have 5х + 6 = 5х;    = 4

 (Divide by 5 on both sides)                         /5          /5= 1   you will get

6=1 that is false

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
