Question

A mining company removes 30 tons of rock from a quarry everyday. If the company works around the clock (24 hours per day), how many pounds of rock are moved every minute? This is a homework question and I need help on it ;-;

30tons/day * 2000lb/ton * 1day/24hr * 1hr/60min = 125/3 lb/min

see how the units cancel out.
