Question

The bells at two churches ring on different schedules. One bell rings every half an hour. The other bell rings every 45 minutes. If both bells rang at 8 AM this morning, what time will it be when the both bells ring again at the same time?

Answer 1

if they ring at 8am and you're trying to find the next time they ring do 45+45=1 hour and 30 minutes and 30+30+30= 1 hour and 30 minutes and you end up with 9:30 am. so your answer is 9:45 AM
