If have being practicing Nav exam questions with . and my question is in regards to the proximity of the multiple choice answers to each other.
Example, i was asked to calculate the estimated time en route to a certain point. I used my flight computer, put in wind calc, TAS etc etc, and got an answer of "47 minutes" The choices i had to choose from were a)44 mins, b)46 mins, C)48 mins and d)50 mins.
I picked 48 minuets based on my calculations with the flight computer, but the answer was 46 minuets.
Are the answers i have to choose from in the transport Canada exam going to be this close together? or am i just doing the calculation incorrect and i need to have a long look at myself in the mirror

If you are interested the question i am am talking about is Question 57 from exam paper 4 on the 2014 . commercial pilot written test book
