The distance P and Q is 9755 m. Two buses A and B start from P and Q respectively towards each other. The speed of bus A and B is 30 m/s and 25 m/s respectively. Bus B started at 2 p.m. from Q towards P and after 5 minutes, Bus A started from P towards Q. Find the time at which both the buses will meet.
The distance P and Q is 9755 m. Two buses A and B start from P and Q respectively towards each other. The speed of bus A and B is 30 m/s and 25 m/s respectively. Bus B started at 2 p.m. from Q towards P and after 5 minutes, Bus A started from P towards Q. Find the time at which both the buses will meet. Correct Answer 41 s
Given:
The distance P and Q is 9755 m. Two buses A and B start from P and Q respectively towards each other. The speed of bus A and B is 30 m/s and 25 m/s respectively. Bus B started at 2 p.m. from Q towards P and after 5 minutes, Bus A started from P towards Q
Formula used:
Distance = speed × time
Calculation:
B started at 2 pm.
In 5 minutes = 300 seconds, distance it covered = 25 × 300 = 7500 m
⇒ Remaining distance = 9755 – 7500 = 2255 m
Relative speeds of A and B = (30 + 25) m/s = 55 m/s
Time taken for them to meet = 2255/55 = 41 s
