Orge welding is a process in which two pieces of steel are joined together by heating the pieces of steel and hammering them together. A welder takes a piece of steel from a forge at 1620°F and places it on an anvil where the outdoor temperature is 70°F. The temperature of the steel T in °F can be modeled by =T+701550e−0.05t, where t is the time in minutes after the steel is removed from the forge. How long will it take for the steel to reach a temperature of 120°F so that it can be handled without heat protection? Round to the nearest minute.
