Question
A train travels a distance at a speed of 80 km/h in 5 hours. What should be the speed of the train if it covers the same distance in 4 hours?Question 2Answera.60kmphb.120kmphc.80kmphd.100kmph
Solution
The distance covered by the train is calculated by multiplying the speed by the time. In this case, the train travels at a speed of 80 km/h for 5 hours, so it covers a distance of 80 km/h * 5 h = 400 km.
If the train needs to cover the same distance of 400 km in 4 hours, we can find the required speed by dividing the distance by the time. So, the speed would be 400 km / 4 h = 100 km/h.
Therefore, the answer is d.100kmph.
