Question

Before the eruption of a​ volcano, the volcano was 2.75 kilometers high. After the​ eruption, the volcano was 2.25 kilometers high. Find the difference in height of the volcano before and after the​ eruption, in meters.

Answer 1

Before the eruption the vulcano was 2.75 km high, what is equal to (2,75x1000) 2750 m. After the eruption it was 2250 meters high. The difference would then be 2750-2250= 500 meters.
