Speeds of two trains are in ratio 5 : 6. The ratio of their times over equal distance is
- 25 : 36
- 5 : 6
- 6 : 5
- 36 : 25
Show answer and solution
Correct answer: C. 6 : 5
For equal distance, time is inversely proportional to speed, so the times are in ratio 6 : 5.
A and B cover the same road in 45 and 30 minutes. The ratio of their speeds is
- 3 : 2
- 4 : 9
- 9 : 4
- 2 : 3
Show answer and solution
