So 567 / 60 = **9.45** MP min.

5699 / **7.45** * 60 = 45,879

yeah, no wonder things are going wrong

speed = 567 mp/h

distance = 5699 miles

taxi = 10 min

sid = 7 min

alt = 4 min

star = 10-15 min

total min waste = 10 + 7 + 4 + 10 = 31 theoretical minutes

total max waste = 10 + 7 + 4 + 15 = 36 theoretical minutes

567 miles/hour div 60 min/hour = 9.45 miles/minute (theoretical)

5699 miles div 9.45 miles/minute = 603.068783069 minutes div 60 minutes/hour = ~10.05 hours (theoretical)

10.05 hours flight time at perfect conditions + 31 minutes of perfect waste (which will never happen at a busy airport such as schiphol) = 10.5678130512 hours = ~ 10 hours and 35 minutes (theoretical)
