<span>Two events in the mid-1760s had a profound effect on Arizona history.

The second was the issuance of a decree by King Charles II of Spain to expel all Jesuits from the Spanish Empire. This latter event required that the Jesuits from the Arizona missions be taken into custody and sent to Mexico City. From there they were sent to Vera Cruz where they were put on ships bound for Europe. Their property, including the missions, reverted to the government.

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,
$\frac32=\frac{220}{8\times3\times d}$
$\implies d=\frac{55}9=6.12$
