The end of the road is 15/16 of a mile away. luke walked 7/8 of a mile down the road. how much further did he need to walk?

1/16 or 0.5/8 of a mile

This is simple to figure out just reverse what they have already simplified. 8 can go into 16 twice. So
8×2=16 
7×2=14
7/8 also equals 14/16
14/16 to 15/16
So... Luke needed to walk 1/16 of a mile.

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.

Oh i'm sorry. didn't see the options
