Two variables, X and Y are said to be in inversely proportional is X*Y - k where k is some non-zero constant.
X and Y are said to be directly proportional if X = c*Y where c is some constant.

Directly proportional. Greater speed - greater distance.
Generally, if y increases as x increases, this is a hint that the quantity is directly proportional, and if y decreases as x increases, the relation might be inversely proportional. However, this is not always the case. x and y are directly proportional if y = kx, where k is a constant. x and y are inversely proportional if y = k/x, k is constant. This is the best way to tell whether the quantities are directly or inversely proportional.
In directly proportional the two variable vary in the same "direction". So, if one increases, the other increases.In inversely proportional, the two variable vary in opposite "directions". So, if one increases, the other decreases.
if two same charg are bring to each other in some force they are repell,it is called inversely propotional.it is true or not?give a correect answer
It is true in the case of inversely proportional relationship.
