Two statements are given below. Select the statement for which a ratio of the measurements is meaningful. State “Neither” or “Both” if appropriate.

Question

1 - Kasheta ran the race in 22.3 sec, and Louisa ran the same race in 26.4 sec.

2 - Juan gets out of school at 2:45 PM, and Aito gets out of school at 3:15 PM.

A. Kasheta ran the race in 22.3 sec, and Louisa ran the same race in 26.4 sec.
B. Neither
C. Both
D. Juan gets out of school at 2:45 PM, and Aito gets out of school at 3:15 PM

an: B

Kasheta speed/Louisa speed = 1.18

Kasheta is 18% faster. That is meaningful.
