Question

8. 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 x time).​

Answer 1

Answer:

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

Step-by-step explanation:

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
