The Mаgicаl Rоck A mаgical rоck lоcated on top of Dragon Mountain is slowly losing pieces of enchanted crystal. The rock loses 18.75 g every 4.25 minutes. Scientists need to collect 3.250 lb of the crystal. Use dimensional analysis to determine how many seconds it will take for the rock to lose 3.250 lb of crystal.(10 points) Useful conversions: 1 lb = 16 oz 1 oz = 28.3495 g 1 min = 60 s
