Question

Marcela estimates the distance between the library and town hall is 735 ft. The actual distance is 612 ft.

Answer 1

Answer:

The error percentage in estimation is 20 %

Step-by-step explanation:

The estimated distance between library and town  =  735 ft

The actual distance = 612 ft

The Error in estimation  =  Estimated Distance - Actual Distance  

                                        =  735 ft -  612 ft  =  123 ft

So, the error in the estimation is 123 ft.

Now,  $\textrm{ Percentage in Error Estimation} = \frac{\textrm{The estimated Error}}{\textrm{The estimated value}} \times 100$

= $\frac{123}{612} \times 100 = 20.098$

or, The error percentage in estimation is 20.09%

Now, rounding off the value to the nearest tenths of a %, we get:

The error percentage in estimation is 20 %
