question

A plane can travel 100 miles per hour (mph) without any wind. Its fuel supply is 3 hours. (This means that it can fly 300 miles without a wind). The pilot now proposes to fly east with a tail wind of 10 mph and to return with, of course, a head wind of 10 mph. How far out can he fly and return without running out of fuel? (The student should first reflect on whether or not the answer is the same as it is without a wind, namely, 150 miles.)
