Question

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?

Answer 1

Kordell, because 14 math problems in 21 Minutes, Compared to 20 Minutes And 12 Math Problems (Gabriel).

Explanation:

Answer 2

Kordell was able to comlpete the most math problems per minute

Explanation:

Number of problems Kordell can solve in 21 minutes = 14 problems

So, number of problems solved per minute = (14/21) problems

= (2/3) problems

Number of problems Gabriel can solve in 10 minutes = 6 problems

So, number of problems solved per minute = (6/10) problems

= (3/5) problems

Now, we need to compare the rate per minute of Kordell and Gabriel.

Comparing
`(2)/(3) \textrm{and}  (3)/(5)`, we get

`(2)/(3)  = 0.666, (3)/(5)   = 0.6`

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
