A cheetah runs 100 metres in 3.5 seconds. A man runs the same distance in 10 seconds. During a 100 metre race, when the cheetah crossed the finishing line, how far back was the man?

• man runs 100m in 10 sec so 10m in 1 second
  distance travelled by man in 3.5 second=35m
  distance travelled by cheetah in 3.5 sec=100m
  man is 100-35=65m back from line

• speed of man=100/10=10m/s
  cheetah takes 3.5 sec to cover 100m
  distance covered by man=10*3.5=35m
  distance between man and cheetah= 100-35=65m

• 100m in 3.5 sec where as another person 100m in 10sec
  x=10-3.5=6.5

• Here, Speed of a man s=100/10 = 10 m/sec..
  so, cheetah crosses a line in 3.5 seconds but that line takes a man to 10 seconds..
  so, in 3.5 seconds the man travels only 35 meters. i.e., 10 m/sec*3.5 sec= 35 meters..
  that means he is lagging the cheetah in 65 meters...
  If you satisfy with my answer.. please choose helpful or not below...
