(D) Total time $= 15\, hours$.$1$. First part: Time $= \frac{1}{3} 	imes 15 = 5\, hours$. Distance $= 5 	imes 80 = 400\, km$.Remaining time $= 15 - 5 = 10\, hours$.$2$. Second part: Time $= 40\% 	ext{ of } 10 = 0.4 	imes 10 = 4\, hours$. Distance $= 4 	imes 70 = 280\, km$.Remaining time $= 10 - 4 = 6\, hours$.$3$. Third part: Time $= \frac{2}{3} 	imes 6 = 4\, hours$. Distance $= 4 	imes 85 = 340\, km$.Remaining time $= 6 - 4 = 2\, hours$.$4$. Fourth part: Time $= 2\, hours$. Distance $= 2 	imes 100 = 200\, km$.Total distance $= 400 + 280 + 340 + 200 = 1220\, km$.
