Answer:
Student-A:
mile/min
Student-B:
mile/min
Student-C:
mile/min
Step-by-step explanation:
Student-A:
she can run 2/3 mile in six minutes
so,
total distance is miles
total time =6 min
we can use formula
speed=(total distance)/(total time)
mile/min
Student-B:
she can run 1/2 mile in 4 minutes
so,
total distance is miles
total time =4 min
we can use formula
speed=(total distance)/(total time)
mile/min
Student-C:
she can run 4/5 mile in 8 minutes
so,
total distance is miles
total time =8 min
we can use formula
speed=(total distance)/(total time)
mile/min
The percent change between the temperature at noon and the temperature at 5:00 p.m. is -20%
The percent change is the relative change between two quantities expressed in percentage.
Given that the At noon, the temperature was 80°F while At 5:00 p.m., the temperature was 64°F. Hence:
Percent change = [(64°F - 80°F) / 80°F] * 100%
Percent change = -20%
Therefore the percent change between the temperature at noon and the temperature at 5:00 p.m. is -20%
