Q: The cheetah is the fastest land animal, capable of attaining a speed of 110km/h . In Augest 2009 , the world record for the men's 100 m sprint was set at 9 58 seconds . how many times is a cheetah as fast as the fastest human sprinter?
plz help me in this question ...
Answers
Answer:
Speed of human sprinter,
Speed = distance/time
= 100/9.58 (m/s)
Converting into kmph
= (100/9.58) * (18/5)
= 37.5 kmph
Cheetah's speed is 110 kmph
110/37.5 = 2.9 = 3
So cheetah's speed is 3 times faster than the speed of human sprinter
Explanation:
Simply calculate the speed of the sprinter in m/s (meters per second). If a man runs, say, 100 metres in 10 seconds, then his speed would be 100 metres / 10 seconds or 10 m/s.
Simply calculate the speed of the sprinter in m/s (meters per second). If a man runs, say, 100 metres in 10 seconds, then his speed would be 100 metres / 10 seconds or 10 m/s.Now, convert meters per second to kilometers per hour: there are 3600 seconds in a hour but 1000 metres in a kilometer, so to convert meters per second you need to multiply them by 3.6 (to convert the other way around, divide by 3.6). For our 10 m/s sprinter that is 36 km/hr.

For our 10 m/s sprinter that is 36 km/hr.Now it's trivial to calculate how many times the cheetah is faster by simply dividing 110 km/hr by 36 km/hr, which comes out as a 3 (and a bit) times faster.

Hope it helps you Mate.
