This is a list of problems that have been solved by MacGyver . Demonstrating resourcefulness, he employs his knowledge of science, technology and outdoorsmanship to resolve what are often life or death crises. His ingenuity is normally put to the test under dire circumstances with little time or specialized resources with which to work. (Though it does seem he frequently has a Swiss Army knife and a roll of duct tape with him.)

√(5-2)^2 + (k-4)^2 = 17 25 + 4 + k^2 + 16 = 17 45 + k^2 = 17 45 - 17 = -k^2 28 = -k^2 √28 Therefore = -5.292

I suppose you mean D1, R1, and T1 are Venus s distance, speed, and time; and D2, R2, and T2 are Shamcey s distance speed and time. Let the units of D1 and D2 be laps; and the units of R1 and R2 be laps/minute. D1 = D2 - 1/4 R1 = 1/4 R2 = 1/3 T1 = T2 Create two speed * time = distance equations: 1/4T1 = D2 - 1/4 1/3T1 = D2 Solve the system of equations: 1/4T1 + 1/4 = D2 1/4T1 + 1/4 = 1/3T1 3/12T1 + 1/4 = 4/12T1 1/4 = T1/12 T1 = 3 minutes Shamcey will catch Venus in 3 minutes.

The travelling salesman problem ( TSP ) asks the following question: "Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city exactly once and returns to the origin city?" It is an NP-hard problem in combinatorial optimization , important in operations research and theoretical computer science.

In the theory of computational complexity , the decision version of the TSP (where, given a length L , the task is to decide whether the graph has any tour shorter than L ) belongs to the class of NP-complete problems. Thus, it is possible that the worst-case running time for any algorithm for the TSP increases superpolynomially (but no more than exponentially ) with the number of cities.

Wood (2003) defines Problem-based learning as a process that uses identified issues within a scenario to increase knowledge and understanding. [3] The principles of this process is listed below:

Problem-based learning has subsequently been adopted by other medical school programs, [4] adapted for undergraduate instruction, [5] [6] [7] as well as K-12. [4] [8] The use of PBL has expanded from its initial introduction into medical school programs to include education in the areas of other health sciences, math , law , education , economics , business , social studies , and engineering. [8] PBL includes problems that can be solved in many different ways depending on the initial identification of the problem and may have more than one solution. [9]

Relative Speed, when the two approaches each other = Speed of Rachel + Speed of Rob = (50 + 70) MPH = 120 MPH To find how many miles apart will they be exactly 45 minutes before they meet, i.e., distance between them in 45 minutes, Apply d = rt Distance in 45 minutes = 120 MPH X (45/60 in hr) miles = 90 miles
