Question

A sign says the distance to the next exit is 5 mi. The actual distance is 5.2 mi. To the nearest percent, what is the percent error of the sign?

Answer 1

4%

Explanation:

vA = actual value

vE = expected value

percent error = ((vA - vE) / vE) x 100

((5.2 - 5) / 5) x 100 = 4

4%

Answer 2

About 4%

because 5 of 5.2 is about 96% so 100% - 96% = 4%
