im having troubles with this(adsbygoogle = window.adsbygoogle || []).push({});

the teacher wants us to find hte instantaneous rate of reaction at time 60 seconds , so i trace 60 s to the graph and make a point where it meets. Now i draw a tangent to this point. This is what gets me, how long should this tangent me, because i kow i have to get the slope of this tangent (that will be my asnwer right) so if i dont nkow how long the tangent should be ill get different rise/run results.

i just want quick instructions

thanks!
