Estimate how many minutes it takes the plane to land to the nearest hundredth o a minute

The height of an airplane during a landing is given by 22,000+(-480t) where t is the time and minutes. Estimate how many minutes it takes the plane to land to the nearest hundredth of a minute.

Height h = 22,000+(-480t)

h = 22000 - 480t

When the plane land then height h becomes 0

So we plug in h=0 and solve for t.

0 = 22000 - 480t ( subtract 22000 on both sides)

-22000 = -480t (divide both sides by -480)

t = 45.833

Airplane takes 45.83 minutes to land
