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 speeds are such that :
A. v1 : v2 $$ = $$ 16 : 25
B. v1 : v2 $$ \ne $$ 4 : 5
C. v1 : v2 $$ \ne $$ 5 : 4
D. v1 : v2 $$ \ne $$ 25 : 16
Answer: Option B
Solution (By Examveda Team)
The two cars will collide if their speed are in the ratio of the distance to do covered by themRatio of distance
= 40 : 50
= 4 : 5
For the cars not to collide :
v1 : v2 $$ \ne $$ 4 : 5
