Time taken by the car is directly proportional to the distance travelled by it (Time ∝ Distance).
• According to the first set of conditions,
Distance covered by the car (d) = 585 km
Time in which the car covered 585 km (t) = 9 h
• Speed of the car (s) = distance / time
=> s = 585 km / 9 h
=> s = 65 km/h
• According to the second set of conditions,
Distance travelled by the car (d') =
520 km
Speed of the car (s) = 65 km/h
Time (t') = ?
• Time = distance/ speed
=> t' = (520 km) / (65 km/h)
=> t' = 8 h
• From the results, it can be concluded that greater the distance, greater the time taken by the car.
Therefore, distance and time are directly proportional to each other.
