You can solve this with proportion

1)    For 2h

9/2 mile : 3/4h = x mile : 2h => (3/4)x=(9/2)*2 => (3/4)x=9 => x=9*(4/3)= 12miles

For 3h => (3/4)x=(9/2)*3 When we divide equation with 3 we get

x/4=9/2 => x=(9/2)*4=18 miles

2)  2 combine : 320 acres = 7 combines : x acres +: 2x= 320*7 =>

x= (320*7)/2 = 160 * 7 = 1120 acres

Good luck!!!
