Unit rate is #0.016bar6# minutes per word

Unit rate is 60 words per minute

Note that the question states particular units. It is good practise to use the same units of measurements in your answer. The words: "each rate" taken to mean 2 conditions Condition 1: Unit is to be 1 word Condition 2: Unit is to be 1 minute. Let the unknown value be #x# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #color(blue)("Solving for condition 1")# Write as a ratio in fractional format #-> ("time")/("word count")-=("time")/1# #5/300 -= (5-:300)/(300-:300) = (0.016bar6)/1=x/1# Unit rate is #0.016bar6# minutes per word ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #color(blue)("Solving for condition 2")# Write as a ratio in fractional format # ("word count")/("time")-=("word count")/1=x/1# #x/1=(300-:5)/(5-:5) =60/1# Unit rate is 60 words per minute ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #color(blue)("Interesting fact")# 60 words per minute #->60/1 # However, if you invert this (turn upside down) then you get the other rate #1/60-> 1-:60 = 0.016bar6#
