Its a long one!
An airliner began its final descent from an altitude of 1.3 miles six minutes before landing. During the descent its speed with respect to the ground averaged 210 miles per hour.
a) What is the equation for the altitude during descent relative to the airport? Assume the relationship is linear. Place your orgin directly under the plane on the ground at the point where it begins its descent. Use y for altitude and x for distance from the airport. Express the expression in standard form with integer coefficients simplified as much as possible.
b) How many miles was it from the airport when the altimeter read 1.1 miles? Enter answer to nearest 10th of a mile. Thank you so much!!
