Consider the formula P= H *d over M, where
• P represents productivity of a camel.
• H represents the area of a hump and is measured in square meters (mº),
• d represents distance a camel can travel, and is measured in meters (m), and
• m represents the mass a camel can carry, and is measured in kilograms (kg).
Select an appropriate measurement unit for productivity of a camel.​
A. M over kg
B. kg over m
C. kg^3 over m
D. M^3 over kg
