Question

very confused on this..i have to solve using an inequality
The troposphere extends from the Earth's surface to a height of 6-12 miles, depending on the location and the season. If a plane is flying at an altitude of 5.8 miles, and the troposphere is 8.6 miles deep in that area, how much higher can the plane go without leaving the troposphere
show me how to do this please

Answer 1

but i need to solve it using a inequality

Answer 2

Ok, well the plan cannot go any higher then 8.6, right? and is currently at 5.8, so, let x be the plane. 5.8<x<8.6

Answer 3

umm ok
