Question

Parvin often cleans the dishes for her mother. She can clean 17 plates in 10 minutes. How many plates can she clean in different amounts of time?

Answer 1

`1.7\cdot{t}`

Explanation:

Parvin can clean 17 plates in 10 minutes, therefore we can determine plates per minutes:

`=17/10=1.7`

1.7 plates per minute. To determine the plates she can clean in t minutes, you must multiply by t minutes:

`=1.7\cdot{t}`

Parvin can wash 1.7t plates in t minutes.

Answer 2

Assuming that the given rate is constant or that it can be used to in ratio and proportion solutions, we can use this to find the number of plates washed in any given amount of time. The formula would be:

17/10 = P/t
P = 17t/10

So, at just replace t in minutes to determine the number of plates washed, P.
