Please can someone tell me, how many times during a 12 hour period, do the hands of a clock face opposite each other? I believe its 11. Also, would this be the same, no matter WHAT the starting time? i.e. if the 12 hour period started at 6 o clock, would it still be 11 times? Many thanks for your help.

A man is travelling with the speed of 10m/min across the river to the opposite bank.The river water flows at the speed of 1m/s.Since the water flows at the speed higher than the boatsman, he would definitley reach the opposite river bank in a slant path.What is the length of the path he travelled?. The river is 10m wide. Please give me solution to tha above probelm. Thanks in advance
