Answer 1

Answer:

here is your answer

Step-by-step explanation:

Answer: Option C

Explanation:

Speed of train relative to jogger = (45 - 9) km/hr = 36 km/hr.

= 36 x 5 m/sec

18

= 10 m/sec.

Distance to be covered = (240 + 120) m = 360 m.

Time taken = 360 sec = 36 sec.

10

correct option is (B)36

Answer 2

Answer:

B) 36 second

Step-by-step explanation:

Speed of train relative to jogger = (45 - 9) km/hr = 36 km/hr.

Speed in m/sec = 36 x 5/18 = 10m/sec

Distance to be covered = (240 + 120) m = 360 m.

Hence,time taken by the train to pass the jogger = 360/10 = 36 sec
