20 m

Step-by-step explanation:

Data provided in the question

Completed desired distance by Arman, Babken, and Cecilla = 100m

At the time of crossing the finish line by Arman, Babken was 10m behind him

And, Cecilla was 10 m behind him when the Babken crossed the finish line

Based on the above information, the distance between Cecilla behind Arman at the time of finish line crossed is

= 10 m + 10 m

= 20 m

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
