L = total lengh, D = number of days
L = 4D + 51 <== ur equation
after 37 days...D = 37
L = 4(37) + 51
L = 148 + 51
L = 199 miles <==
Do the Pythagorean theory to find the unknown side by doing:
c^2 = a^2 - b^2
Then you’ll have two sides and two angles.
Do sine law.
Sin(angle) / side (opposite to it) = Sin(angle) / side (opposite to it)
18r + 24

The X intercept(s): (-4,0) and (0,0)
The Y intercept(s): (0,0)
99 km ... 9 liters
x km ... 12 liters
If the relationship is proportional, we have
from where
The answer is 132 kilometers.
