Q1. An oil burner uses 76 gallons of fuel per hour. At 9 a.m., there are 266 gallons on hand. At noon, no oil has been delivered. What is the maximum amount of time the burner can continue to run without more oil?
Answer: ½ hour
Explanation: By noon (3 hours later), 3×76=228 gallons are used, leaving 266−228=38 gallons. At 76 gal/hr, this lasts 38/76 = ½ hour.
