Answer 1

Answer:This is the answer. Please mark as brainliest.

Step-by-step explanation:

Relative speed of 2 bodies moving towards each other = Sum of the speed of the 2 bodies.

Therefore, relative speed = 110 + 90 km/hr = 200 km/hr ( Option A)

Answer 2

Answer:

200 km/hr

Step-by-step explanation:

1)when two train moves towards each other their relative speed is the sum of their speed.

2)when two train moves in the same direction then their relative speed is the difference of their speed.
