A train travels a distance of 360 km in 4 hours. If the train increases its speed by 10 km/h, how much time will it take to cover the same distance?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 3.6 h.
Distance = 360 km
Time = 4 hours
Speed of train: 360 ÷ 4 = 90 km/h
New speed: 90 + 10 = 100 km/h
New time: 360 ÷ 100 = 3.6 hours
So, the train will take 3.6 hours or 3 hours 36 minutes.
