Let the distance covered at 40 kmph be x km

⇒ Time = distance/speed = x/40

Given that as he increased his speed by 16 kmph, then he covered 80 km more

⇒ Time = (x + 80)/(40 + 16)

⇒ Time = (x + 80)/(56)

Also given that time is same in both the cases

⇒ x/40 = (x + 80)/56

⇒ 56x = 40x + 3200

⇒ 16x = 3200

⇒ x = 200 km

∴ Actual distance covered = 200 km
