Question
260 metre long train ‘A’ can cross a platform of
length 180 metres in 16 seconds. If the speed of train ‘B’ is 6 m/s more than that of train ‘A’, then find the distance travelled by train ‘B’ in 5 hours.Solution
Speed of train ‘A’ = {(260 + 180)/16} = (440/16) = 27.5 m/s Speed of train ‘B’ = 27.5 + 6 = 33.5 m/s = 33.5 × (18/5) = 120.6 km/hr Required distance travelled by train ‘B’ = 120.6 × 5 = 603 km
