You finish 3 homework problems in 10 minutes, your friend finishes 9 homework problems in 1/2 hour. are you and your friend working at the same rate?

Yes because 3 home work problems takes 10 min and 10x3 =30 and that’s a half hour

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.

X> -2 is the simplified version.
