Question
A train covers a distance of 10 km in 12 minutes. If its speed is decreased by 5 km /hr, the time taken by it to cover the same distance will be :__________?
Answer: Option D
SPEED = (10 X 60/12 ) KM/HR = 50 KM/HR. NEW SPEED = (50 – 5) KM / HR = 45 KM /HR. SO TIME TAKEN = ( 10/45 ) HR = ( 2/9X 60 )MIN 131/3 MIN = 13 MIN 20 SEC.
