Show answer & explanation
Correct answer: B
Answer:
3.75
Explanation:
As the two cars are moving towards each other,
their relative speed will be = 15+30 = 45 kmph.
The distance between them 5 minutes before crossing
will be equal to the distance travelled by their relative speed in 5 minutes,
i.e. Required distance = Relative speed (in km per min) * time (in minutes) = (45/60)*5 = 3.75 km.
