Question

The city manager in a New England town which has 4900 miles of streets is examining the productivity of the snow removal operations during the winter months. The town keeps track of the number of trucks, the total number of gallons and the total number of miles traveled for sno removal. The data for 2006 and 2007 are provided in the following table: Measure of Performance 2006 2007 City miles 4900 4900 Number of trucks 4800 4000 Gallons of gasoline used Number of miles travelled For the productivity measure city miles/truck, what is the percent change from 2006 to 20077 Specify as a signed number with two decimal digits without a percent sign 22000 240001 Answer: I Check

Explanation / Answer

Productivity is defined as ratio of output to input:

P = output/input

Truck productivity = city miles/number of trucks utilized

Truck productivity in 2006 = P1 = 4900 miles /22 trucks = 222.73 miles/truck

Truck productivity in 2007 =P2 = 4900/19 = 288.24 miles/truck

Percentage increase in truck productivity is given as follows:

% increase = (P2 - P1) / P1 x 100

=(288.24 - 222.73)/222.73 x 100

= 29.41%

Percentage increase in trucks productivity from 2006 to 2007 is 29.74%
