4 4/7

Step-by-step explanation:

You multiply the n by 7 first because you are cross multiplying. So it would be 7n = 32.

So to simplify you would divide 32 by 7 to get n= 4 4/7

4 4/7 is a mixed number 4 is the whole and 4/7 is the fraction just to clarify

Or as a fraction it would be 32/7

step-by-step explanation:

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
