assuming efficiency of each man to dig trench, in one day, for one hour is constant,
so one man, working for one hour in one day can dig 1.5 m
so 8 men, working 3 hours a day and will take, say $d$ number of days and efficiency will be constant. so,
$\frac32=\frac{220}{8\times3\times d}$
$\implies d=\frac{55}9=6.12$
Technology caused the Industrial revolution because the main point of the IR was the fact that the US became more modernized and were able to produce more for less. In the industrial revolution, both were achieved with the use of mass-production, which made most of the mass-produced products more affordable for more people, and so the sellers sold more.
the Industrial revolution affects our society today, because without the sudden invention of many things (cars, typewriters, railroads) we wouldn't be a world power as we are today. Also, without the IR, we may have lost more wars throughout the years then we actually did
hope this helps
5-10 i think vro, thats what ive seen from most people
