(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A furlong is and old British unit of length equal to 0.125 mi, derived from the length of a furrow in an acre of plowed land. A fortnight is a unit of time corresponding to two weeks, or 14 days and nights. Find the speed of light in megafurlongs per fortnight. (one megafurlong equals a million furlongs).

2. Relevant equations

speed= distance/time

fur=0,125 mi

for=2 weeks

mg= 1,000,000 fur

3. The attempt at a solution

1 mf/ 1,000,000 fur x 1 fur/0.125 mi x 0.125 mi/ 1fur x 2w/1 for = ... i'm stumped here. i cant understand which way to set it up so that i am only left with mf/for
