Answer:

3.33 meters per second

Step-by-step explanation:

1 1/2 laps = 200+100 = 300

use formula: distance = rate x time

t = time (in meter per second)

300 = 90t

t = 300/90 which reduces to 3.33/1

Divers in a competition are scored by an international panel of judges. The highest and the lowest scores are dropped. The total
Fudgin [204]

From the statements given in the problem, we can say that:

 

Final Score = (total of the remaining scores) * degree of difficulty * 0.6

 

Therefore:

97.2 = (total of the remaining scores) * 4.0 * 0.6

total of the remaining scores = 40.5

 

Therefore the judges could have scored which has a total of 40.5
