Achef uses 3 and 3 fourth of flour and 1 and 5 eighth pounds of whole wheat flour for each batch of pasta she makes. one week she uses a total of 86 pounds of flour. how many batches of pasta does she make

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
