Answer:
Time taken to travel the same distance at 45 km/h is 4 hours.
Step-by-step explanation:
Speed = 40 km/h
Time = 4.5 hours
Therefore distance = Speed x Time = 40 x 4.5
Distance = 180 km
____________________________________
New speed = 45 km/h
Distance = 180 km
Therefore, time taken = Distance / Speed = 180 / 45
Time taken = 4 hours
