Solution


(a)
Time taken by car to cover 165 km = 3 hours
∴ Time taken by car to cover 1 km = 3165=155 hours
⇒ Time taken by car to cover 330 km = 155×330 = 6 hours
Thus, the time taken by car to cover a distance of 330 km is 6 hours.
(b)
Distance covered by the car in 3 hours = 165 km
∴ Distance covered by the car in 1 hour = 1653 = 55 km
⇒ Distance covered by the car in 8 hours = 55 × 8 = 440 km
Thus, the distance travelled by the car in 8 hours is 440 km.
