Answer:
Before we begin, first convert the minutes unit to seconds to match the unit for speed. Since there are 60 seconds in a minute, and there are 3 minutes, 3*60 = 180 seconds. Using the formula s = d/t, we can manipulate this formula to solve for d, the distance. So we isolate the d variable, to get d = st, and we can substitute the values of s and t into this formula. Now we have d = 4m/s*180s. Now we solve this to get d = 720m. Now we can convert meters to miles, to get approximately 0.45 miles.

Explanation: Well, think about it if you see it on the logical end, there are 8 men that mean 16 legs. Then there are 4 legs of the couch as well that made it total of 20. If broken legs are of the men, then still the total will be 20 because the legs are still intact but 6 men left that means 12 legs are gone, if 3 legs break and 6 men leave. the number of legs remaining are 20–6*2–3=5.... so it's 5 I hope this helps! xoxo
