Q. Rick's chore list shows that he is responsible for washing the dishes after dinner this week. Last night, he washed 4 plates in 2 minutes. Tonight, his grandparents are coming to dinner, and Rick will wash 6 plates.If he washes plates at the same rate, how many minutes will it take Rick to wash the plates tonight?____ minutes
Calculate Rate: Calculate the rate at which Rick washes plates. He washed 4 plates in 2 minutes, so the rate is 2 plates per minute.
Determine Time: Determine how long it will take Rick to wash 6 plates at the rate of 2 plates per minute. Time = Number of Plates / Rate =6 plates /2 plates per minute =3 minutes.
