Answer» Correct Answer - Option 1 : 30 km Given, Speed of a boat, b = 10 km/hr Speed of current, s = 2 km/hr Time = 2.5 hours (in downstream motion) Formula Used: Downstream speed = (b + s) Distance covered = Downstream speed × time Calculations: Let D be Downstream speed Downstream speed, D = 10 + 2 = 12 km/hr Distance covered = 12 × 2.5 Distance covered = 30 Km ∴ The distance covered by the boat in downstream in 2.5 hours is 30 Km |
