an online recipe for sugar cookies calls for 3/5 cup of margarine for each batch. You are making a half batch of cookies for your small group. How much margarine do you need?

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

it would open into a square depending on the type of envelope i’m not sure about the second part
