Question #794b6 Algebra Linear Equations Equations with Ratios and Proportions 1 Answer Akazukin 赤ずきん · Stefan V. Nov 6, 2017 #210# words. Explanation: #120# words per minute can be expressed as #2# words per second because there are #60# seconds in a minute, and #("120 words")/("60 seconds") = ("2 words")/("second")# #"1.75 minutes" xx "60 seconds" = "105 seconds"# If Dorothy types #2# words per second, then in #105# seconds, she will type #210# words. #"2 words"/"second" xx "105 seconds" = "210 words"# Answer link Related questions What is the difference between proportions and ratios?
