Ans. 1) It is now 4:39. Brian has to wait 9 minutes for his train (to New-burgh ) Amy has to wait 18 minutes for her train (to Springfield ) while Stephanie has to wait 36 minutes for her train ( to Clarksville).
Ans. 2) The answer is 43. Simply add up 10+65+58 getting a total of 133 then subtract 90 to get the answer. The reason this works is that when you add up 10, 65 and 58 you are double counting the people with experience in both sales and publishing so just subtract the original number if applicants 90 and you are left with the experienced people - single counted , just the way you want.
