A) 30 s
B) 40 s
C) 50 s
D) 60 s
Correct Answer: A
Solution :
Relative velocity of overtaking \[=40-30=10\,m/s\] Total relative distance covered with this relative velocity during overtaking \[=100+200=300m\] So, \[\text{time}\,\text{taken}\,\text{=}\,\frac{\text{300}}{\text{10}}\,\,\text{=}\,\text{30}\,\text{s}\]You need to login to perform this action.
