i) Distance travelled in 20 minutes : ⇒ 75 60 = x 20 ⇒ x = 75 × 20 60 = 25 km Thus, the train will cover a distance of 25 km in 20 minutes. [1.5 marks] (ii) Time required to cover a distance of 250 km: ⇒ 75 60 = 250 y ⇒ y = 250 × 60 75 = 200 minutes Thus, a distance of 250 kilometres will be covered in 200 minutes. [1.5 marks] Atrain travelled at a speed of 35 km/hr for the first 10 minutes and at a speed of 20 km/hr for the next 5 minutes. The average speed of the train for the total 15 minutes is (1) 30 km/hr (2) 23 km/hr (3) 31 km/hr (4) 29 km/hr. View Answer. Ans . (1) 30 km/hr. Explanation : Answerlink. Truck travels 120 kilometers per hour. . THat is the speed. In one minute truck will travel 2 K M.So in 60 minutes ( 1 hour) it will travel 120 KM. h) A car drives for 2 hours 54 minutes at a speed of 50 mph (i) A plane Wlies at a speed of 306 kilometres per hour for 3 hours 20 minutes (j) A hot air balloon Wlies at a speed of 18 mph for 1 hour 40 minutes (k) A bird Wlies for 4 hours 36 minutes at a speed of 40 kilometres per hour.
