Two cars are moving with speeds v1 and v2 towards a crossing along two roads. If their distances from the crossing be 40 m and 50 m at an instant of time, then they do not collide, if their speeds are such that
v1 : v2 ≠ 4 : 5
v1 : v2 ≠ 5 : 4
v1 : v2 ≠ 25 : 16
v1 : v2 ≠ 16 : 25
A certain distance is covered at a certain speed. If half of this distance is covered in double the time, the ratio of the two speeds is
4 : 1
1 : 4
2 : 1
1 : 2
