SOLUTION: How do you use derivatives and linear approximation (the formula for linear approximation being L(x)=D(1-(x/60)) at the point x=0) to approximate the amount of time it takes to d

Question 928752: How do you use derivatives and linear approximation (the formula for linear approximation being

====================
I don't.
Just use d= r*t
t = d/r
