Hey there, I hope this helps :D

Remeber, P/E/M/D/A/S (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract)

So, do 3x2= 6 divided by 12

Which equals to 6+2+9 = 18

18+ 82 = 100 - 7 = 93 (You can calculate the answers just in case to see if its correct)

Hoped this helped! :)

step-by-step explanation:

abc

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
