Answer:
Isaiah can drive 144 more miles before he runs out of gas.
Explanation:
First, we know that with a full tank, Isaiah can drive 360 miles. This means that half a tank will allow him to drive half that distance, or 180 miles.
Second, we know that after driving for 3 hours, Isaiah has half a tank left. We don't know his speed, but we know that whatever speed he is driving, he has used half a tank of gas to cover the distance he has driven in those 3 hours.
Third, we know that after stopping for refreshments, Isaiah drives 36 more miles. This distance is subtracted from the remaining 180 miles he could drive on half a tank.
So, to find out how much longer Isaiah can drive before he runs out of gas, we subtract the 36 miles he has already driven from the 180 miles he could drive on half a tank.
180 miles - 36 miles = 144 miles
So, Isaiah can drive 144 more miles before he runs out of gas.
