Suppose you are driving from work to home on a highway. Variables speed (X) and time (Y) for your trip to get home are inversely proportional. So, we can write: Y= K/X,  where K is called constant of proportionality. It took you 2 hours to get home from work, and your speed was 55 miles/hour, what is the value of constant K? 22.5 110 None of these answers
