Velocity vs Tool Life curve using Taylor’s Tool Life equation for n of 0.5 and C of 400

Question: In a machining test, a cutting speed of 100 m/min indicated the tool life as 16 min, and a cutting speed of 200 m/min indicated the tool life as 4 min. What are the values of n and C? [ESE 2016] This is a straightforward problem on tool life that can be solved simply by using Taylor’s Tool Life equation. Here, two cutting velocities and the corresponding tool life
