the problem reads th quantity of charge q that has passed through a surface area of 2.00cm^2 varies with time accoding to the equation(adsbygoogle = window.adsbygoogle || []).push({});

q=4t^3+5t=6 where t is in seconds. what is the instantenaus current through the surface at t=1s?

What I did was plug in 1 in the equation and got 15 as an answer, then to get current (I) i did I= q/t so that gave me 15 the answer in the book is 17. how did they get this?

thanks in adavance
