How many millimeters (mm) would be equivalent to a length of 18.34 furlongs? Present answer in scientific notation rounded to the proper number of significant figures.

Answer 1

1 meter = about 0.005 furlongs = 5 x 10^-3 furlongs

1 mm = 0.001 meters= 1 x 10^-3 meters

1 mm = 1 x 10^-3 x 5 x 10^-3 = 5 x 10^-6 furlongs

1 furlong = 1/(5x10^-16) mm

= 2 x 10^15 mm

18.34 furlongs = 18.34 x 2 x 10^15 = 36.68 x 10^15 = 3.67 x 10^16

18.34 furlongs = 3.67 x 10^16 mm
