A processing machine crushes 3 1/4 kilograms of dried fruits in 3/4 minutes. what is the rate ,kilograms per min, at which the machine crushes dried fruits?
To find the rate at which the machine crushes dried fruits, we need to divide the amount of dried fruits crushed by the time it takes to crush them.
Amount of dried fruits crushed: 3 1/4 kilograms = 13/4 kilograms
Time taken to crush: 3/4 minutes
Rate = amount/time = (13/4) / (3/4) = 13/3 = 4 1/3 kilograms per minute
Therefore, the rate at which the machine crushes dried fruits is 4 1/3 kilograms per minute.
