Water in a canal, 5·4 m wide and 1·8 m deep, is flowing with a speed of 25 km/hour. How much area can it irrigate in 40 minutes, if 10 cm ofstanding water is required for irrigation ?
A train travels 180 km at a uniform speed. If the speed had been 9 km/hour more, it would have taken 1 hour less for the same journey. Find the speed of the train.
Represent the following pair of equations graphically and write the coordinates of point where the lines intersect y-axis. x+3y=6 and 2x−3y=12
