If I had one clock that chimes every half hour and the other every 15-minutes and they both chimed together at 1. the next time they will chime to gether will be two oclock pm
They'd chime together at 1:30.
Can you explain how to do this problem. Thanks
The clock that chimes every half hour chimes at 1:00, 1:30, 2:00, etc.
The clock that chimes every 15 minutes chimes at 1:00, 1:15, 1:30, 1:45, 2:00, etc.
30 minutes is 1/2 hour
15 minutes is 1/4 hour
