Can someone plz me get the answer with 5,6 and 8 ? i'm having trouble.

5.) 48 Minutes (Note: you must complete the drawing)
6.) 2/3 of the children have red or brown hair.
7.) Abdul spent $4.28
8.) No, because if you add up the distance from the home to the store and back you get 1/2 mile and if you add from home to the library and back you get 1/5 of a  mile, which when you add them together you get 7/10 which is not equal to a mile.

What does h hours mean
