80%of parts produced at some factory have high quality but the remaining 20% are of low quality. A high quality parts fails within 5 years with probability 0.1. For a low quality part, this probability is 0.4. if one part is randomly selected what is the probability that it fails within 5 years.

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.
