A fast food restaurant uses a conveyor belt to send the burgers through a grilling machine. If the grilling machine is 1.1 m long and the burgers require 2.5 min to cook, how fast must the conveyor travel? If the burgers are spaced 15 cm apart, what is the rate of of burger production (in burgers min)? For the first question: Distance of belt=rate×time to cook Which gives me. 0.44 m/min However, the second part is giving me problems. I did 1.1m=0.15mB+(o.44 m/s + Db) (2.5 min-B) which is wrong. Any hint?
