A train moves from City A to City B, a distance of 180 Kilometres in 3 hours. If the train keeps running at the same constant rate, how many hours will it take to travel the distance between City C and City D, which are 720 Kilometres apart?
Show answer & explanation
Correct answer: C
Explanation
Distance from City A to City B = 180 km
Time = 3 hours
Therefore, speed of the train = 180 ÷ 3
= 60 km/h
Distance from City C to City D = 720 km
Time required = 720 ÷ 60
= 12 hours
