City time + country time = 3 hours
t=d/r
D(city)=x
speed = 24
D(country)=(147-x)
speed = 54

LCD = 216 Multiply by LCD
AMP Parsing Error of [(9x+(4*147)-4x=216*3]: Invalid expression. Closing bracket expected =216*3 at /home/ichudov/project_locations/algebra.com/templates/Algebra/Expression.pm line 187. .

9x+588-4x=648
5x=60
/5
x=12 miles in the city
Balance =>147-12= 135 miles in country
