Answer: B is travelling in higher speed
Explanation:
Distance covered by A = 2.5 km
Time taken by A = 30 mins = 1/2 hr
Hence, speed of A = distance /time
= 2.5 ÷ 1/2
= 2.5 x 2
= 5km/hr
Distance covered by B = 5km
Time taken by B = 45 mins = 3/4hr
Hence, speed of B = distance/time
= 5 ÷ 3/4
= 5 x 4/3
= 20/3 ≈ 6.67 km/hr
Since, 6.67 > 5 , speed of B is more than A

Total distance covered = 16 km
total time required = 15 min = 41 hr
We knw
Speed = TimeDistance
Speed = 1/416=64 km/h
Hence speed of train is 64 km/h
