Scott likes to run long distances. He can run 20 km in 85 minutes. He wants to know how many minutes (m) it will take him to run 52 km at the same pace. How long will it take Scott to run 52 km?

221 km.

Step-by-step explanation: Figure out how many minutes it takes him to complete one km. That is 4.25 minutes for one km. Now for 52 km just times 4.25 to 52 and the answers turns into 221km.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
