The speed metrics of two moving trains are in the ratio 4 : 5. If they cover an identical route length, and the slower train tracks it in 2.5 hours, find the time parameter for the faster train. MCQ with Answer and Explanation
The speed metrics of two moving trains are in the ratio 4 : 5. If they cover an identical route length, and the slower train tracks it in 2.5 hours, find the time parameter for the faster train.
A. 1.8 hours
B. 2.4 hours
C. 2.0 hours
D. 2.2 hours
Answer: Option C
Solution (By JKSSB Mock Tests)
Ratio of speeds = 4:5, so ratio of times taken = 5:4. Slower train takes 5 parts = 2.5 hours => 1 part = 0.5 hours. Time for faster train = 4 parts = 4 * 0.5 = 2.0 hours.
