Q:

Kordell is able to complete 14 math problems in 21 minutes. Gabriel is able to complete 6 math problems in 10 minutes. Who was able to comlpete the most math problems per minute?

Accepted Solution

A:
Answer:Kordell was able to comlpete the most math problems per minuteStep-by-step explanation:Number of problems Kordell can solve in 21 minutes = 14 problemsSo, number of problems solved per minute =  (14/21) problems= (2/3) problemsNumber of problems Gabriel can solve in 10 minutes = 6 problemsSo, number of problems solved per minute =  (6/10) problems= (3/5) problemsNow, we need to compare the rate per minute of Kordell and Gabriel.Comparing[tex]\frac{2}{3} \textrm{and}  \frac{3}{5}[/tex], we get[tex]\frac{2}{3}  = 0.666, \frac{3}{5}   = 0.6[/tex]and 0.666  > 0.60⇒ (2/3) > (3/5)Hence, the rate per minute of Kordell is greater than that of Gabriel.Hence, Kordell was able to complete the most math problems per minute
