In a dog training Camp, a dog trainer trains the dog by the name of Mr. Smith, to run. On the first command he moves one sixth of the total distance. On the second command, he runs half of the remaining distance. On the third command, he runs one fifth of the remaining distances. On the fourth commands, he runs third quarter of the remaining distances. On the final command he runs 60 cm. What distance, in meters, did Mr. Smith covers in his training?

Mr. Smith covers 60 × 4 × 5 4 × 2 × 56 = 720 60\times4\times\frac54\times2\times56=720 centimeters, which is equal to 7.2 7.2 meters.

Interesting, how each of the fractions come?

Answer
= (60/100) * 1/(1-3/4) * 1/(1-1/5) * 1/(1-1/2) * 1/(1-1/6).
= 0.60 x 4 x 5/4 x 2 x 6/5.
= 0.6 * 12.
= 0.72m
