| Two trains start at the same time from points x and y towards each other and after crossing, they take 9 h and 4 h in reaching points y and x, respectively. Find the ratio of speeds of the 1st train to that of the 2nd train. |
A) 2 : 3
B) 3 : 2
C) 2 : 5
D) 5 : 3
Correct Answer: A
Solution :
| Given that, \[{{T}_{1}}=9\,\,h\] |
| and \[{{T}_{2}}=4\,\,h\] |
| According to the formula, |
| (Ist train's speed): (IInd train's speed) |
| \[\sqrt{4}:\sqrt{9}=2:3\] |
