From point H, at 6: 30 pm, a train starts moving towards point K at the speed of 90 km/hr. Another train starts moving from point K at 7: 30 p.m. towards point H at the speed of 72 km/hr. Both trains meet at 11:30 p.m. at point J. What is the ratio of the distance between HJ and KJ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 25 : 16.
Distance = time × speed
So, the ratio of the distance between HJ and KJ = (5 × 90) : (4 × 72) = 25 : 16
