Asurvey indicated that 3 out of 5 doctors use brand x aspirin. if 2000 doctors were surveyed, how many used brand x

First of all 2000 is divided by 5 and then multiplied by 3 .
           =2000/5*3
           =400*3
           =1200 
                      is the required answer .
1200 doctors uses the brand X .

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.
