Plz solve
process se
first we have to find distance so formula d = speed × time then d = 72×6 then d = 432 now the second speed is 15m/s so we have to convert it into kilometre per hour then (15×18)/5 then 54km/h now we have to find time so time = distance/ speed, then time = 432/54, and then 8 hours is your answer
