Question

a machine grinds two sevenths pound of spices in 1 third of a second. what in the machines rate, in pounds per second of grinding spices

Answer 1

So we know the following from the given information about the grinding speed:\[\frac{ 2 }{ 7 }lbs/\frac{ 1 }{ 3 }\sec\]That tells us that the machine grinds at a rate of 2/7 pounds every 1/3 seconds. What can we do to the top and bottom in order to make the bottom 1 second isn't of 1/3?
