3.5/6.5=15/60
0.53846153846153846153846153846154 a minute
15/60=.25 every min
so it is filling at 0.28846153846153846153846153846154 a minute.
68/28846153846153846153846153846154=235.73 minutes to reach the limit which is almost 4 hours 3.9288888888888888888888888888889 hours
165 /3.9288888=39.7059 kmph
