Home Assignment: Quadratic Equations : Home Assignment: Quadratic Equations For what value of k the quadratic equation x2 –kx + 4 = 0 has equal roots? Some students arranged a picnic. The budget for food was Rs 240.Because four students of the group failed to go, the cost of food to each student got increased by Rs 5. How many student went for the picnic? If a person had walked 1 km∕hr faster, he would have taken 15 minutes less to walk 3 km. Find the rate at which he was walking? A motor boat whose speed is 18 km∕hr in still water takes 1 hour more to go 24km upstream than to return downstream to the same spot. Find the speed of the stream.
