Question

Mr. Ignacio went diving along the coral reef in Oahu. He descended 12 meters below the sea. The difference between this point on the coral reef and the tallest point on the island, Mt ka'ala is 1,232 meters. The ranger station is 2/5 up the mountain. How far above sea level is the ranger station?

Answer 1

488 meters above sea level.

Explanation:

Since the difference between that point and the tallest point is 1,232 you need to subtract 1,232 - 12 = 1,220 to get how far Mt ka'ala is from sea level. Since the ranger station is 2/5 up the mountain you can do 1,220/5 = 244. This is 1/5 of the way up the mountain. Then you do 244 x 2 = 488. That is 2/5 up the mountain. Final answer: The ranger station is 488 meters above sea level.

Answer 2

488

Explanation:

so 1232-12 and you get 1220 and 2/5 of 1220 is 488 so its 488 levels above sea level
