A team of construction engineers are measuring the length of the new highway they want to build to the nearest mile. The greatest possible error of any measurement is 0.8 miles.
If they measure a highway that is 400 miles long, what is the percent error of their measurement?
A team of engineers are measuring the speeds of cars to the nearest kilometer per hour. The greatest possible error of any measurement is 0.9 kilometers per hour.
If they measure a car traveling 100 kilometers per hour, what is the percent error of their measurement?
A scientist is measuring the melting temperature of a metal to the nearest degree Celsius. The greatest possible error of any measurement is 0.5 degrees Celsius.
If the scientist is measuring a metal that has a melting temperature of 350 degrees Celsius, what is the percent error of his measurement?
A physicist is measuring the power of a light bulb to the nearest Watt. The greatest possible error of any measurement is 0.7 Watts.
If the physicist is measuring a light bulb that has a power of 60 Watts, what is the percent error of his measurement?
An electrician is measuring the current of an electric circuit to the nearest Amperes. The greatest possible error of any measurement is 0.1 Amperes.
If the electrician is measuring a circuit that has a current of 0.9 Amperes, what is the percent error of his measurement?
An engineer is measuring the resistance of an electric circuit to the nearest Ohm. The greatest possible error of any measurement is 0.5 Ohms.
If the engineer is measuring a circuit that has a resistance of 240 Ohms, what is the percent error of his measurement?
John is measuring the weight of a box to the nearest pound. The greatest possible error of any measurement is 0.3 pounds.
If John is measuring the weight of a box that has 120 pounds, what is the percent error of his measurement?
