Question

in a volcano, erupting lava flows continuously through a tube system about 12 kilometers to the sea. Assume a lava flow speed of 0.5 kilometers per hour and calculate how long it takes to reach the sea

Answer 1

24 h

Explanation:

Formula

speed = distance / time

speed = 0.5 km/h

distance = 12 km

time = ?

then we clear time in the equation

time = distance / speed

time = 12 / 0.5

time = 24 h
