Hey there!

Richard has 480 dollars.

Giving 1/4 of the money to his brother would mean giving 120 dollars to his brother.

Richard has 480-120, or 360 dollars left.

Giving 1/3 of the money left would be giving 120 dollars to his sister.

His sister and brother both got 120 dollars from Richard.

Hope this helps, and let me know if you need more help. :)

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

no idea
