- 24

Answer 2

Antonio is at -24 meters where ocean floor is at -94 meter So from the ocean floor he is 94 – 24 = 70 meter above.

Solution:

Given that ocean floor is at -94 meter.

Antonio has reached -12 meters. He is continuously moving down.

Number of meters he moves down in one minute = -4m

Number of meters he moves down in 3 minutes = Number of meters he moves down in one minute
`*` 3

Number of meters he moves down in 3 minutes =
`-4 * 3` = -12 meters.

After here minutes Antonio reached to -12 + -12 = -24 meters.

So Antonio is at -24 meters where ocean floor is at -94 meter .So from the ocean floor he is 94 – 24 = 70 meter above
