Question

If a plane loses 1400 feet in altitude over a horizontal

distance of 8000 feet, what is the slope?

Answer 1

Slope (m) =

ΔY

ΔX

=

1

1

= 1

θ =

arctan( ΔY )

ΔX

= 45° =

1

4

π

ΔX = 8000 – 1400 = 6600

ΔY = 8000 – 1400 = 6600

Distance (d) = √ΔX2 + ΔY2 = √87120000 = 9333.8095116624
