A volcano has erupted near a populated city in Hawaii. The lava is flowing at a constant speed of .25 m/s. The nearest village is approximately 2 kilometers away. How many minutes do the villagers have to evacuate before the lava reaches their home? ( Please show the steps to do the problem)

.25 m/s = 1 m/4s
1 km=1,000 m
2 km=2,000 m
4s x 2,000=8,000s
8,000/60 (to convert to minutes)= 133 minutes and 20 seconds.

This is a simple time-speed-distance problem. The lava is flowing at 0.25 meters per second, and must go 2000 meters. The obvious division gives 8000 seconds, or a bit over two hours.
