Question

In a valcano, erupting lava flows continuously through a tube system about 19 kilometers to the sea. assume a lava flow speed 0.5 kilometer per hour and calculate how long it takes to reach the sea.

Answer 1

Lava flows continuously about 19 kilometers to sea if speed of  lava is 0.5 kilometer per hour then it will take 38 hours to reach the sea.

As given,

Distance covered = 19kilometers

Speed of lava = 0.5 kilometer per hour

0.5 kilometers=1 hour

⇒ 1kilometers = (1/0.5)hour

⇒ 19 kilometers = (19 / 0.5) hour

⇒ 19 kilometers = 38 hours

Therefore, lava flows continuously about 19 kilometers to the sea if speed of the lava is 0.5 kilometer per hour then it will take 38 hours to reach the sea.
