Question

C&A operates three eight-hour shifts to produce 600 gallons of a chemical per day. It requires 12 minutes of labor to produce a gallon of the chemical. What is C&A’s takt time in minutes per gallon and target manpower?

0.3, 40

0.8, 15

0.04, 5

2.4, 5

Answer 1

3 eight hour shifts produce 600 gallons. So, 1 eight hour shift will produce 600 $\div$ 3 = 200 gallons.

So, as 8 hrs produce 200 gallons, 1 hour or 60 mins produce 200 $\div$ 8 = 25 gallons.

12 minutes of labour is required to produce 1 gallon, so in 1 hour 1 labour can produce 60 $\div$ 12 = 5 gallons of chemical.

So, to produce 25 gallons, we need 25 $\div$ 5 = 5 labours.

Again as we already know in 1 hour we can produce 25 gallons, the time taken for producing 1 gallon overall (not per labour) is 60 $\div$ 25= 2.4. This is the takt time (time taken per unit of material).

So, the answer is option d i.e. 2.4,5
