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?

2.8 miles higher the plane go without leaving the troposphere?

Step-by-step explanation:

Troposphere height on different locations = 6-12 miles

plane altitude at present flight = 5.8 miles.

Troposphere deepness from the present flight = 8.6 miles

So from present altitude till troposphere = 8.6-5.8 = 2.8 miles
