    The answer to this question is the next common multiple of 15 and 35.So the next common multiple is 5*3*7 = 105 min Since the start time is 7 AM, the bus that leaves every 15 minutes will leave at 7 Am + 105 min = 8:45 AM The bus that leaves every 35 min will leave at the same time 8:45.So the next time when these 2 buses will leave the station at the same time is 8:45 AM
