Assume that all chickens have 4904 feathers. If it takes you 1.9 seconds to pluck 69.8 feathers, how many hours would it take you to defeather 5157 chickens?Answer in units of hours.
start doing the conversion from chickens to time. Its easy if you watch the units. I'll use c for chicken and f for feather. Thus, we have
5157c * 4904f/c * 1.9s/69.8f * 1hr/3600s = 191.2 hr
