Question

A soccer field is 120 yards long. Han measures the length of the field using a 30-foot-long tape measure and gets a measurement of 358 feet, 10 inches. What is the amount of the error? Express the error as a percentage of the actual length of the field. 13.3

Answer 1

Answer:

The answer to your question is 0.33

Step-by-step explanation:

Data

Actual length = 120 yd

Han's measure = 358 ft 10 in

Process

1.- Convert Han's measure to yards

              1 ft ---------------- 0.333 yd

           358 ft --------------  x

               x = (358 x 0.333) / 1

               x = 119.32 yd

              1 in ---------------  0.028 yd

             10 in -------------  x

              x = 0.28 ft

Total feet = 119.32 + 0.28

                = 119. 6 yd

2.- Calculate the error

% error = (119.6 - 120) / 120 x 100

% error = |-0.4|/120 x 100

% error = 0.0033 x 100

% error = 0.33
