Dishwasher Rate


Problem: A dishwasher cleans 1350 dishes in 1 hour. How many dishes will it wash in 16 more minutes? 1. Find the washing rate in dishes per minute. We convert 1 hour to minutes. $1\text{ hour }= 60\text{ minutes}$ We compute the rate by dividing total dishes by total minutes. $$1350 \div 60 = 22.5$$ So the rate is $22.5$ dishes per minute. 2. Compute the number of dishes washed in 16 minutes. Multiply the rate by 16 minutes to find the output in that time. $$22.5 \times 16 = 360$$ Thus the dishwasher washes $360$ dishes in 16 minutes. 3. Final answer. Therefore the dishwasher will wash $360$ dishes in 16 minutes.
