A car moves at a uniform speed of (x + 30) km/hr. Find the distance covered by the car in (y + 2)hours.(Hint: distance = speed × time). |
Answer» Speed of the car = (x + 30) km / hr. Time = (y + 2) hours Distance = Speed × time = (x + 30) (y + 2) = x(y + 2) + 30 (y + 2) = x (y + 2) + 30 (y + 2) = (x) (y) + (x) (2) + (30) (y) + (30) (2) = xy + 2x + 30y + 60 Distance covered = (xy + 2x + 30y + 60) km |
