"""One morning it started to snow, and the snow fell steadily for the rest of the day. At

noon a snowplow started to clear a road at a constant rate in terms of the volume of snow removed per hour. The snowplow had cleared 2 km by 2 o’clock and 1 more km by 4 o’clock. When did it start snowing?""" !math
