Question

A cyclist estimates that he will bike 80 miles this week. He actually bikes 75.5 miles. What is the percent error of the cyclist's estimate? Round the percent to the nearest hundredth if necessary.

Answer 1

5.96

Explanation:

Answer 2

6%

Explanation:

Estimated distance = 80 miles

Actual distance covered = 75.5 miles

We need to find the percent error of the cyclist's estimate. Its formula is given by :

`\%=\frac{|\text{actual value-estimated value}|}{\text{actual value}}* 100`

Put all the values,

`\%=(80-75.5)/(75.5)* 100\\\\=5.96\%`

or

= 6%

So, the percentage error is 6%.
