Question

Sunny and his friends went for a picnic in the hills. They camped at 2500 m above the sea level. From the camp they walked 500 m away on a level ground. Then they climbed to the hill top which is 90 m vertically higher. There they walked 100 m on level ground on the ledge of the hill. Then they came down to a plane ground 40 m below. How high is this plane ground from the sea level?

Answer 1

Answer:

2550m

Step-by-step explanation:

They camped at 2500m above sea level and then they walked a straight level(same height and even surface) of 500m (which has same sea level of 2500m). Then they climbed a 90m vertical hill and then they came down to a level ground 40m below the vertical hill.

Therefore,

2500+90= 2590

2590-40=2550

Therefore, they are the land of 2550m above sea level.
