प्रश्न
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).
उत्तर
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) + (x)(2) + (30)(y) + (30)(2)
= xy + 2x + 30y + 60
Distance covered = (xy + 2x + 30y + 60) km
