20 seconds

is it right answer

Answer 2

I think so by mistake you have written 15 two times as option B and C both...

The correct answer of this is 25.

Solution:

Total Distance = (200 + 100) m = 300 m

Speed = 54 km/h = 54 × 5/18 m/sec

Time = Total Distance/Speed

Required time = (300/54×5) × 18 = 25 sec

Answer:

25 sec

Hope it helps!!
