<span>Group A (distance in miles) 1 1.5 3.03 3.2 2.8 1.5 1.8 2.5 2.2
Group B (distance in miles) 2 2.5 3.23 1.3 1.8 2.4 3 1.5 1.8
Group A mean = (1 + 1.5 + 3.03 + 3.2 + 2.8 + 1.5 + 1.8 + 2.5 + 2.2)/9 = 19.53/9 = 2.17
Group B mean = (2 + 2.5 + 3.23 + 1.3 + 1.8 + 2.4 + 3 + 1.5 + 1.8)/9 = 19.53/9 = 2.17
Therefore, the mean is equal for Group A and Group B.

Well I would look up all the steps online but you have to divide like 10 then multiply
Answer:
a 56.25 minutes
b 9.6 miles
Step-by-step explanation:
To find the rate, we take the miles and divide by the minutes
rate = 8 miles / 50 minutes
.16 miles per minute
A. how long to run 9 miles
We want to use the formula
d =rt where d is the distance, rate is the rate and t is the time
9 = .16 *t
Divide each side by .16
9/.16 = .16/16 *t
56.25 = t
It will take 56.25 minutes
B We have a time of 1 hour
We want to use the formula
d =rt where d is the distance, rate is the rate and t is the time
t = 1 hour, but our rate is in minutes
1 hour = 60 minutes so t = 60 minutes
d = .16 * 60
d =9.6 miles
