Since he observed that the team has average of 45 seconds, then it is observational study
Square root of 6 is 2.44 so place the dot at the the 2.4 place.
6/10 x 10/1
6 x 10 = 60
10 x 1 = 10
60/10 = 6
1/2 x 10/1
1 x 10 = 10
2 x 1 = 2
10/2 = 5
3/4 x 20/1
3 x 20 = 60
4 x 1 = 4
60/4 = 15
The least common multiple (LCM) of 36 and 200 is: 1800
36 × 50 = 1800
200 × 9 = 1800
