Ed Davis drove all day through Qasvin and into the night
until he reached the Abas-Abas village. If we assume that Ed started at around 8AM-10AM and
drove until about 8PM-9PM after the sun
went down in late July, "We arrived at Abas-Abas' village after
dark" as Ed said, that is around
10-13 hours of driving. Also, Bob Cornuke stated that Ed drove at least 8-12
hours the first day before
arriving at Abas-Abas' village.
The son of Abas-Abas drove Ed in a British lorry
starting at around 10PM-Midnight until 6AM-9AM in the morning, "through the night into the
morning sometime," which is around 6-11 hours of driving.
The total time in driving was around 16-24 hours. The
entire distance on the existing 1943 roads from Hamadan through Qazvin to Mount Ararat is 838
kilometers or 520 miles.
At an
average of 40 miles per hour (mph), it would take about 13 hours to cover the
520 miles.
At an average of
30 miles per hour (mph), it would take about 17.3 hours to cover the 520
miles.
Even
at an average of 25 miles per hour (mph), it would only take about 20.8 hours
to cover the 520 miles,
which fits comfortably near the middle of the estimated 16-24 hours of total
driving time.
If one assumes the longest possible driving time being 24 hours, then the
Army truck and the British
lorry would only need to average 21.67 miles per hour over the distance.
