Core TradesCâu 36 / 700
An air-conditioning unit is rated at 36,000 Btu/hr of cooling capacity. Since one ton of cooling equals 12,000 Btu/hr, what is its capacity in tons?
a.2 tons
b.3 tons
c.4 tons
d.5 tons
Giải thích
Dividing 36,000 by 12,000 gives exactly 3 tons of cooling. 2 tons would be 24,000 Btu/hr and 4 tons would be 48,000 Btu/hr, so only 3 tons matches the rating.
