A and B move towards each other at the same time at the speeds of 10 km/h and 20 km/h, respectively and the distance between them is 49 km. How much is the distance between them, in m, 5 minutes before they meet?
Answer & explanation
Correct answer: option 3
Speed of A = 10 km/hr
And speed of B = 20 km/hr
Relative speed(when moves in opposite direction) = 10 + 20 = 30 km/hr
Now, distance covered in 60 mins = 30 km
So, distance covered in 5 mins = \(\frac{30}{60}\) × 5 km
= 2.5 km = 2500 m
So , The distance between them 5 min before they meet is 2500 m
