You are performing a dye trace study in which you add some dye to a recharge area of the Norton Aquifer and monitor various wells drilled into the aquifer to watch for the dye to appear.You have determined that the effective velocity of groundwater in the Norton Aquifer is 7.5× 10^-⁷m/s,and you are monitoring wells at distances of 0.5 m (Well A),2 m (Well B),and 100 m (Well C)from the recharge area.When do you expect the dye to appear at each well site? A)Well A = ~7 days,Well B = ~30 days,and Well C = ~4 years B)Well A = ~6 seconds,Well B = ~3 seconds,and Well C = ~133 seconds C)Well A = ~1.5× 10 ^{^-⁶}seconds,Well B = ~3.75× 10 ^-⁷seconds,and Well C = ~7.5× 10^-⁹ seconds D)Well A = ~7 years,Well B = ~30 years,and Well C = ~4 years

Question

The time for the dye to travel to each well is calculated by dividing the distance by the velocity. For Well A (0.5 m), it takes ~7.7 days; for Well B (2 m), it takes ~30.8 days; and for Well C (100 m), it takes ~4.2 years.
