thanks for requesting my help
I'll post the solution in 1-2 mins
The easiest way to do it is to go to the relative reference frame.the anular velocity of one person with respect to another is (1.7+3.4)*10^(-3)=5.1*10^(-3) rad./secnow one full revolution is 2PI rad, hence the people will meet in2PI/5.1*10^(-3) =1232 sec
hope this helps
Answer: 1232 sec or rounding you get 1200 sec
please do not hesitate to request me in the future, I'll be glad to assist.
