Answer:
150 seconds
Step-by-step explanation:
use the velocity equation of

Where V is in feet per second, Delta D represents the change in displacement and delta t represents the change in time
all you need to do is rearrange the equation to find Delta(T)
as such...

Width = w
Length = 2.5w
Area of Rectangle: Width × Length
w (2.5w) = 2250
2.5w^2 = 2250
w^2 = 2250/2.5 = 900
w = Sq rt of 900 = 30
l = 75
Ratio of inches to ft
x/30 = 160/2250
cross multiply: 2250x = 160 × 30
2250x = 4800
x = 4800/2250 = 2.13333...
length
x/75=160/2250
2250x = 75(160)
2250x = 12,000
x= 12,000/2250
x = 5.3333...
scale is 2.13" × 5.33"
Rise over run would be your slope sooo your slope is one that what I got
The answer is H=1 to this one I think.
