section 2.5 problems

• 1 just rewrite into y=k/x form
• 2 solve for k to make the equation, then use the equation 
• 3 use the equation 
• 4 
• define x and y
• solve for k
• if k is the same for each of the three situations then it is inverse. If k is different it is not inverse variation
• 5 "time it takes to travel a given distance is inversely proportional to how fast you travel". The distance you travel is constant so it is k. The "time" and the "how fast you travel" (speed) are y and x.
