percentage error = 7.14%

Step-by-step explanation:

Hank's speedometer reads 60 miles per hour, but during a road test he finds the he was actually driving 56 mph.

estimated / read value = 60 miles per hour

actual value/correct value = 56 miles per hour

error = estimated or read value - correct value/actual value

error = 60 - 56 = 4 mph

percentage error = error / correct value * 100

percentage error = 4/56 * 100

percentage error = 400/56

percentage error = 7.1428571429%

percentage error = 7.14%
