Hi Bobbyboo,
Determine the altitude to be lost, divided by the horizontal distance to be flown expressed as X ft per nm. (approx 360 ft / mile in your example). Plot your table with distance from VOR versus Altitude using X ft per mile. (From your known start point.)
ROD on 3 deg slope at 140 kts ground speed = approx. 700 ft / min (half the GS trick * 10) Your 3.54 slope is about 20% steeper so add 20% to get required ROD from 3 deg trick. (700 + 140 = 840 ft per min)
