If we knew that 500 families living in various cities were surveyed randomly to gather this data, is it possible to make a valid conclusion?

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.

1. 3/6 or 1/22. 1/123. 1/84. 1/105. 2/12 or 1/6
