Dunno and Donut flew to the moon in a spaceship. The ship flies in a straight line at a speed of 128 thousand kilometers per hour. In order not to get depressed, Donut needs to eat one donut every 15 minutes. How many donuts can a Donut eat before the ship arrives on the moon? The donut that Donut ate at the time of take-off does not count, the moon is 384 thousand kilometers from Earth
The ship will fly to the Moon at this speed 384/128 = 3 hours exactly. In three hours, 3 * 60/15 = 12 intervals of 15 minutes will pass. Since at the end of each of these intervals Donut will eat a donut, he will eat 12 of them.
