Mean: add all the numbers, then dived the sum by hwo many numbers there are.
72.3 + 74.5 + 81.1 + 72.3 + 75.6 + 79 = 754.8
754.8 ÷ 6 = 75.8
Mean = 75.8°
Median: Put all the number in order from lowest to highest. The middle number is the median. If there are two numbers in the middle, add them then divide the sum by 2.
72.3, 72.3, 74.5, 75.6, 79, 81.1
74.5 + 75.6 = 150.1
150.1 ÷ 2 = 75.05 ~ 75
Median = 75°

Answer:</h2>
- Trip to work has rate: 24 mph
- Trip back to home has rate: 18 mph
- Distance to work is: 480 m
<h2>
Step-by-step explanation:</h2>
We know that speed is defined as the ratio of distance to time.
i.e.
Let the distance traveled to work be: x m.
Now, while going to work it takes a person 20 minutes.
This means that the speed of the person while going to work is:
Also, the time taken to come back home is: 30 minutes.
This means that the speed of person while riding to home is:
Also, it is given that the rate back is 8 mph slower than the trip to work.
This means that:
i.e.
Hence, the distance to work is: 480 m.
Also, the rate while going to work is:
and the trip back to home is covered with the speed:
