Question

a car moves at at a uniform speed of(x+30)km/hr.find the distance covered by the car in (y+2) hrs.​

Answer 1

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) + (x) (2) + (30) (y) + (30) (2)

= xy + 2x + 30y + 60

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