If I'm travling 90 miles per hour and hit a 60 foot ramp, that stands 16 feet tall. How far would I travel ?

I assume the ramp is inclined downward.

In that case just caculate the time required for a body to come vertically down from height of 16ft and initial velocity is zero. (acceleration = g = 32)

s = ut + 1/2 at^2

16 = 1/2 32 t^2

t = 1 sec

In 1 second, your horizontal velocity being 90 mph = 132 ft per second,

Hence you will travel a horizontal distance of 132 feet, and verticle distance downward of 16 ft. That is, until you hit the ground.
