Bolt has run 45.28s for 400m.
The 100y is rarely run outside the US, however, it is likely that Bolt will have passed the 100y mark in his best 100m race in around 8.75s.
Usain Bolt's fastest recorded speed during a race was 27.8 mph (44.72 km/h), achieved during his world record-setting 100 meters at the 2009 World Championships in Berlin. In that race, he finished with a time of 9.58 seconds, solidifying his status as the fastest man in history. This incredible speed showcases his exceptional athleticism and sprinting ability.
my 1997 Geo Metro acts the same way, I was able to figure out that it was a fuel problem because I sprayed some carburetor cleaner into the air filter compartment and it started, it would keep running as long as I kept spraying. I mentioned it to a mechanic friend and he suggested I replace the fuel pump relay. Based on my own experience with other cars, when its time to replace the relay it is usually time to replace the fuel pump too, because it might be starting to have a problem that causes the relay to overload.
That's fascinating ! I never heard of that before, and it's something to think about. I have an idea of an answer. It's only my opinion, and a speculation at best: The runner's time in 100 meters is made of two components: 1). His 'cruising' speed, and 2). How fast he can accelerate off the blocks, from zero to cruising speed. The time in the 100m starts with the pistol, so the acceleration off the blocks starting from zero speed is included in the final result of the run. The result of the 4x100 is comprised of 4 individual cruising speeds, but only one acceleration from the blocks. The other three runners accelerate before the hand-off, and each of them covers his full 100 meters at his full cruising speed. I'll bet you it's that three-less starts off the blocks that's responsible for the startling discrepancy that that you have pointed out. And even so, man ... the discrepancy is only 0.02 second. What do you want ? ! Look, look, look ! . . . . . -- Bolt's record in the 100m is 9.58 -- Four times that is 38.32 -- The US ran 4x100 in 38.3 That means Bolt could get down on the blocks, and on the average, any one of those four guys could stand behind Bolt, get his running start up to his max sprint, and as he passed Bolt at full speed, Bolt could leave the blocks, and he would be only 0.02 second behind the other guy after 100 meters !
