One day, Dario hiked 834 feet up a mountain. On the same day, Demetrius went scuba diving and descended 68 feet below the surface of the water. What is the difference between Darius And Demetrius' elevation?
834 +68 =902 feet
Is this feet
since all the data are given in feet, I'd say, yes, this is feet.
It also happens to be the right number of feet, in case that's what's on your mind.
