National highway speed =x
State Highway speed =x-4
336/x = 224/x-4
336x -336*4 =224x
336x - 1344 = 224x
1344 = 112x
1344/112 =x
x= 12
State highway =12-4 =8
State Highway speed =x-4
336/x = 224/x-4
336x -336*4 =224x
336x - 1344 = 224x
1344 = 112x
1344/112 =x
x= 12
State highway =12-4 =8

using ratios here makes it simpler and easy.
national:state
336:224
3:2
1part = 4
therefore, national = 3*4
state = 4*2 = 8
national:state
336:224
3:2
1part = 4
therefore, national = 3*4
state = 4*2 = 8
