Problem

At this year's Olympic Games in Paris, the men's 100m sprint was won by American Noah Lyles in 9.784s, Jamaica's Kishane Thompson finished second by five thousandths of a second. Lyles ran on the track number 7, Thompson on the track number 4. Sprint is started by the report of the starter's gun firing. Every runner has a speaker right behind their starting blocks to ensure they all hear the sound at the same time. However, if they started at the sound of a real gunshot fired from a pistol located near lane 1 at the start line, by how much time would Thompson have won? The width of a lane is 1.22m.
