Answer:
Step-by-step explanation:
Firstly, you have to know that
There are 10 equally-spaced hurdles on a race track. The first hurdle is 13.72 meters from the start line. The final hurdle is 14.02 meters from the finish line. The race track is 110 meters long
If total length is 110m
First hurdle and last hurdle is 13.72+14.02=27.74m
So the hurdles is evenly distributed at 110-27.74=82.26m
And there are 10 hurdles which will occupy 9 spaces distance
So each hurdle are places
82.26/9=9.14m
So each hurdle is at a distance of 9.14m.
Now, the runner takes 3 strides between each hurdle and he leaves the ground 2.2 m before the hurdle and 1m after the hurdle, this show that, the total distance of hurdle minus the distance in air is what he travelled,
Then, distance travelled is
Hurdle distance - distance in air
9.14-3.2=5.94m
So he took 3 strides
Then, each stride is 5.94/3=1.98m
So, the runner each stride is 1.98m
