The distance between two cities A and B is 330 km. A train starts from A at 8 a.m. and travels towards B at 60 km/hr. Another train starts from B at 9 a.m. and travels towards A at 75 km/hr. At what time do they meet?
-
- 10 a.m.
- 10 : 30 a.m.
- 11 a.m.
- 11 : 30 a.m.
Correct Option: C
Distance travelled by first train in one hour
= 60 × 1 = 60km
Therefore, distance between two train at 9 a.m.
= 330 – 60 = 270 km
Now, Relative speed of two trains
= 60 + 75 = 135 km/hr
∴ Time of meeting of two trains
| = | = 2 hrs. | |
| 135 |
Therefore, both the trains will meet at 9 + 2 = 11 A.M.
