A missile travels at 1350 km/hr. How much metres does it travel in one second? A student goes to school at the rate of 2 ½ km/h and reaches 6 min late. If he travels at the speed of 3 km/hr, he is 10 min early. What is the distance to the school? A car travels at a speed of 60km/hr and covers a particular distance in 1h. How long will it take for another car to cover the same distance at 40km/hr? Two trains of same length, are running in parallel tracks in opposite directions with speed 65 km/hr and 85 km/h respectively. They cross each other in 6s. The length of each train is A boatman takes twice long to row a distance against the stream as to row the same direction with the stream. Find the ratio of speeds of the boat in still water and the stream. Watch the solution in video
