Four automatic insertion machines are set up in series to add components to printed circuit boards. Each machine inserts 20 different component types. Due to board design and component requirements, automatic setup and insertion times for machines are uniformly distributed with a mean of 4 minutes and a coefficient of variation of 0.5. Assume machines do not fail. Estimate the production rate per hour if buffers of size 2 are added between each pair of machines. Round answers to 1 decimal place.
