I do not have specific information on Jason Robinson's 100m time. However, he is a former professional rugby player known for his speed and agility, so he likely had a competitive time in the 100m.
100m in 20s = 300m in 60s = 1 minute so 300m x 60min = 18000m in 1hour Answer: 18 kilometres per hour
the fastest time is 35.67 seconds.
100m freestyle Michael phelps 46.65 seconds
Not sure of 100m time, but aware that he clocked 40.1 kms/per hour (25mph). source Ben Ryan England coach.
