Answer: √74 or 8.6

Step-by-step explanation:

Formula for distance is √ [ (x2 – x1)^2 + (y2 – y1)^2].
A(3,9) and B(8,2)
√[(8-3)^2+(2-9)^2]
Put that into a calculator and you get √74 which can be rounded to 8.6

Jason and Eddy are traveling from Jacksonville to Miami, which is a distance of 382 miles. According to the American Automobile

wolverine [178]

Answer:

The value is $v = 49.23 \ mph$

Step-by-step explanation:

From the question we are told that

The distance from Jacksonville to Miami is d = 382 miles

The time it take to travel from Jacksonville to Daytona is $t_1 = 1 \ hour\ and\ 54\ minutes = 1 + \frac{54}{60} = 1.9 \ hours$

The time it take to travel from Daytona Beach to Fort Pierce is $t_2 = 2\ hours\ and\ 51\ minutes= 2 + \frac{51}{60} = 2.85 \ hours$

The time it take to travel from Fort Pierce to West Palm Beach is

$t_3 = 1\ hour\ and\ 23\ minutes= 1 + \frac{23}{60} = 1.38 \ hours$

The time it take to travel from West Palm Beach to Miami $t_4 = 1\ hour\ and\ 38\ minutes= 1 + \frac{38}{60} = 1.63 \ hours$

Generally the average speed is mathematically represented as

$v = \frac{d}{t_1 + t_2 +t_3 + t_4 }$

=> $v = \frac{382}{1.9 + 2.85 +1.38 + 1.63 }$

=> $v = 49.23 \ mph$
