Step-by-step explanation:

Put this into numbers:

Use Order of Operations to simplify. First, you would do the stuff in parentheses which is:

Inside of those parentheses first simplify the exponents:

Now add

So the new equation is:

The next step is to simplify the exponents

Multiply out the top

Divide this

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
