When the rabbit falls one kilometer behind the tortoise, it chases the tortoise at the speed of 101 M / min, but the tortoise still crawls at the speed of 1 m / min. how many minutes does it take for the rabbit to catch up with the tortoise Who knows?

If the tortoise is stationary, the speed of the rabbit is 100 m / min
T = x / v = 1000 / 100 = 10 (minutes)
