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.
