A jug holds 10 pints of milk. If each child gets one cup of milk, it can serve
children. (Hint: 1 cup = 8 fluid ounces and 1 pint = 16 fluid ounces.)

There are cups in a pint. This means we can multiply a number of pints by to find the number of cups.

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
