A line completes 420 units during 7.0 operating hours. Average throughput is most nearly:
- (A)60 units/h
- (B)75 units/h
- (C)90 units/h
- (D)120 units/h
Show worked solution
Answer: (A)
Throughput is 420/7=60 units per hour.
The process, inventory, or flow relation determines system performance.
Substitution and unit reduction give the reported value.

Why the other choices appear
- (B)This introduces an extra factor of 1.25 that is not present in the governing relation.
- (C)This value is 50% above the verified result; no stated conversion creates that change.
- (D)The units are retained, but an unsupported 2 multiplier changes the requested magnitude.
