Amelia likes to make desserts for bake sales. Last month, she made 1 batch of brownies and 2 batches of cookies, which called for 7 eggs total. The month before, she baked 3 batches of brownies and 3 batches of cookies, which required a total of 12 eggs. How many eggs did Amelia use for a batch of each dessert?

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
