Question

Hanks speedometer reads 60 mph but during a road test he finds that he was actually driving 56 mph what is the percent error

Answer 1

The percent error in the speeds are 7.1428 %.

Explanation:

The percent error of any value is found by,

`error percent = ((|(reading value)-(correct value)|)/(correct value))(100)`

Here, the reading value is 60 mph and the correct value is 56 mph.

Hence inserting this value in above equation, we get

`error percent = ((|(60)-(56)|)/(56))(100)`

`error percent = 7.1428 %`

Hence, the percent error in the speeds are, 7.1428 %.
