Teaching plan of mathematical tortoise and rabbit race
Rabbit 10 runs 330 * 10 = 3300m, and tortoise 2 10 runs 30 * 2 10 = 6300m. Let the rabbit catch up with the tortoise after waking up for x minutes: 330 * 10+330x = 30. At this time, the distance of the rabbit is 330*( 10+ 10)=6600 meters, and the distance from the finish line is 7000-6600=400 meters.
