Aboat can go 20 km upstream and 30 km downstream in 3 hrs. It can go 20 downstream and 10km upstream in 1 hrs 40 min . Find the speed of the boat in still water and speed of the stream. View Solution. Q3. A motorboat travels 30 km downstream in 3 hours and 40 km upstream in 5 hours. Find the speed of the boat (in km/hr).

Solution Step 1: The formula for distance is. Distance = Rate × Time. Total distance = 50 × 3 + 60 × 2 = 270. Step 2: Total time = 3 + 2 = 5. Step 3: Using the formula: Answer: The average speed is 54 miles per hour. Be careful! You will get the wrong answer if you add the two speeds and divide the answer by two.

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 : Howfar will you get if you travel 40 mph for 20 minutes? If you're travelling at 40 mph, how long will it take to go 48 miles? A car travels 24 km/h. How far does it travel in 20 minutes? Tourists covered 255 km for a 4-hour ride by car and a 7-hour ride by train. What is the speed of the train, if it is 5 km/h greater than the speed of the car? Atrain travels at a speed of 30 km per hour for 12 minutes and then for the next 8 minutes at a speed of 45 km per hour then the average speed for the journey is. A. 36 km/hr. B. 37 km/hr. C. 38 km/hr. D. 40 km/hr. Open in App. next 40 km with 20 km/hr and then 90 km at 15 km/hr, then find his average speed for the whole journey (in km/hr)

Atrain starts from rest and moves with a constant acceleration of 2.0 m s 2 fbr half a minute. The brakes are then applied and the train comes to rest in one minute. Find.
