Question 181087: If distance travelled is inversely proportional to the square root of the time taken, and distance is 13 m, after 9 sec, then the constant of proportionality is? Answer by eperette(173) (Show Source):
You can put this solution on YOUR website! Concept you should know:
Inverse proportion y=k/x
where y,x are variables and k is constant of proportionality
********
d=k/sqr(t)
13=k/sqr(9)
13=k/3
13*3 = k/3 * 3
39 = k
constant of proportionality, k, equals 26
