1,187 bu/hr
1,255 bu/hr
1,522 bu/hr
1,178 bu/hr

Respuesta :

Answer:

1,187 bu/hr

Step-by-step explanation:

4.8 mi/hr

240 inches

Efficiency: 85% (0.85)

120 bushels/acre

1 acre = 6 272 640

1 mile = 63 360 inches

4.8 miles = 304 128 inches

120/6 272 640 x 240 = 5/1089 (bushels/inch)

5/1089 x 304 128 x 85% = 1 186.9 = 1187 bu/hr

Wow, that's hard for me :) Hope it's helpful
