FIND THE NUMBER OF METERS IN 1.00 MILE

Question

I NEED HELP CALCULATING THE ANSWER FOR THIS QUESTION SHOWING ALL THE POSSIBLE METHODS AND WORKINGS FOR THIS PROBLEM ABOVE .

Answer 1

Everyone knows that the meter's length is rigorously defined. There  used to be a platinum bar in Paris with two lines scribed on it that defined the meter. Now I think they use wavelengths of light.

 

But did you know that the English system of inches, feet, yards, etc., is just as rigorously defined? It is, because the inch is defined to contain EXACTLY 2.54 centimeters.

 

(5280 feet/mile)(12 inches/foot)(2.54 cm/in)(1 meter/100 centimeters)

 

= 1609.344 meters/mile, exactly.

Answer 2

Hi Malissa;

(1.00 miles)[(1609.34 meters)/(1.00 mile)]

The units of miles is in the numerator and denominator.  It cancels...

(1.00 miles)[(1609.34 meters)/(1 mile)]

1609.34 meters
