    Hi everybody,
    
    Your opinion and/or solution to a nav-question (from an old examination).
    
    Here it is:
    
    In ploting sights taken on 3 stars, you get an erronous PR at L 47? 50.0'N,
    Lo 088? 10.0'W.  What will be the exact PR if after revising all
    calculation you detect the following errors and correct them:
    
    A.      The chronometer was 30 seconds slow instead of 30 seconds fast .
    
    -------------------------------------------------------
    
    B.      The Greenwich Date was the one day later.
