Speed = Distance / time taken
Speed = 100m / 10 sec
Speed = 10 m/ s.
For mph (miles per hour);
1 mile = 1760 yards.
1 yard = 0∙9144 meters
Speed = 10m/ sec.
1 hour = 3600 sec.
1 mile / 1760 yds * 1 yds / 0∙9144meters * Speed * time =
1 mile / 1760 yds * 1 yds / 0∙9144meters * 10m/1sec * 3600sec / 1 hr =
mph = 22∙369 362 92...
mph ≈ 22∙37

100/10=10m/s
in an hour 10*3600=36000m/hour=36km/hour
1km=0.6214mile
36*0.6214=22.37mile/hour
