A processing machine crushes 3 1/4 kilograms of dry fruits in 3/4 minute. What is the rate, in kilograms per minute, at which the machine crushes dry fruit?
A. 3/13
B. 16/39
C. 2 7/16
D. 4 1/3
To find the rate at which the machine crushes dry fruit, we need to divide the amount of dry fruits crushed by the time taken.
3 1/4 kilograms / 3/4 minute
= 13/4 / 3/4
= 13/4 * 4/3
= 13/3
= 4 1/3
Therefore, the rate at which the machine crushes dry fruit is 4 1/3 kilograms per minute.
Therefore, the answer is D. 4 1/3.
