Two cars are moving with speed v1, v2 towards a crossing along two roads. If their distance from the crossing be 40 metres and 50 metres at an instant of time then they do not collide if their speed are such that
-
- v1 : v2 = 16 : 25
- v1 : v2 ≠ 4 : 5
- v1 : v2 ≠ 5 : 4
- v1 : v2 = 25 : 16
Correct Option: B
Let time taken be equal
| i.e., | = | , then | ||
| V1 | V2 |
they will collide i.e. cars will reach at the same time.
| ∴ | ≠ | = | |||
| V2 | 50 | 5 |
