Question

in how much time will a 160 metre long train running at 66 kilometre per hour passes a cyclist running at 6 kilometre per hour in the opposite direction in which the train is going​

Answer 1

length of train = 160m (given)

Step-by-step explanation:

travelling in opposite direction so to get relative speed ,both's speed will be added.

relative speed = 66 + 6 = 72km/h

= 72 × 5/18 = 20 m/s

required time = 160/20

= 8 Seconds
