1. Marcus can type 40 words in half a minute. Rhys can type 100 words in one and a half minutes. Which student can type at a greater rate of words per minute?
if Marcus can type 40 words in half a minute, then 40 times 2 equals 80. 80 words a minute for Marcus. If Rhys can type 100 words in 1 1/2 minute, 100/ 1.5 = 66.66 and 80>66.66 so Marcus can type a greater rate of words per minute.
