Question
A train covers a certain distance at a speed of 60 kmph in 20 hours. To cover the same distance in 3 hours, It must travel at the speed ofA)600kmphB)300kmphC)400kmphD)350kmph
Solution
First, let's find out the total distance covered by the train. We can do this by multiplying the speed of the train by the time it traveled.
So, Distance = Speed x Time = 60 kmph x 20 hours = 1200 km
Now, to find out the speed needed to cover the same distance in 3 hours, we divide the total distance by the time.
So, Speed = Distance / Time = 1200 km / 3 hours = 400 kmph
Therefore, to cover the same distance in 3 hours, the train must travel at the speed of 400 kmph. So, the answer is C) 400 kmph.
