Two trains starting at the same time from two-stations 300 km apart and going in opposite directions, cross each other at a distance of 160 km from one of them. The ratio of their speeds is :

Explanation:-

A → ___160________Meeting____140_____← B
Ratio of their distance covered = ¹⁶⁰/₁₄₀ = 8:7
Then,
Ratio of their speeds = 8:7 [When time is constant Speed is proportional to Distance covered]
