Question

A bicycle’s speedometer measures speed to the nearest 0.1 miles per hour. Which is the most appropriate way to report speed using the bicycle’s speedometer?

A.) 17MPH
B.)17.1 MPH
C.) 17.15 MPH
D.) 20 MPH

Answer 1

The bicycle`s speedometer measures the speed to the nearest 0.1 mph. So 17.15 mph is not appropriate way to report speed, because then it should measure speed to the nearest 0.05 mph. Also 17 mph and 20 mph are whole numbers and it does not have to be so accurate. 
Answer:  B. 17.1 mph
