Answer:
0.8 cm
Step-by-step explanation:
The formula for MAD is attached in the picture.
x_i are the values (data)
x bar is the mean
n is the number of numbers (data)
For figuring out MAD, basically, <em>we subtract the mean from each of the values respectively and take the absolute value and SUM for all of the numbers in the data set. Then we divide by n, the number of numbers.</em>

Let's do this:
MAD =
MAD is 0.8
Alright, lets get started.
Suppose the speed to the ranch = x mph
So, speed to the ocean will be = (x-4) mph (because the speed was 4 mph less than the speed to the ranch)
Distance to the ranch = 888 miles
time moving to the ranch
time moving to the ranch
time moving to the ocean
As per given in question, the 888 mile trip to the ranch took three times as long as the 280 mile trip to the ocean , means
Corss multiplying
Hence speed to ranch = 74 mph
Hence speed to ocean = mph
time for trip to ranch = hrs
time for trip to ocean = hrs
So, speed to ranch is 74 mph and trip time is 12 hrs and speed to ocean is 70mph and time is 4 hrs.
Hope it will help :)
