Two places R and S are 800 km apart from each other. Two persons start from R towards S at an interval of 2 hours. Whereas A leaves R for S before B. The speeds of A and B are 40 kmph and 60 kmph respectively. B overtakes A at M, which is on the way from R to S. What is the extra time taken by A to reach at S?
  • a)
     6hrs 20 minutes
  • b)
    6hrs 40 minutes
  • c)
    6hrs 30 minutes
  • d)
    6hrs 10 minutes

Verified Answer
Two places R and S are 800 km apart from each other. Two persons start...
Time taken by A to reach at Q = 800/40 = 20 hours
Time taken by B to reach at Q = 800/60 = 13 hours and 20 min
A takes 6hr 40 minutes extra time to reach at Q.

Two places R and S are 800 km apart from each other. Two persons start...
Problem Statement:
- Two places R and S are 800 km apart from each other.
- Two persons start from R towards S at an interval of 2 hours.
- A leaves R for S before B.
- The speeds of A and B are 40 kmph and 60 kmph respectively.
- B overtakes A at M, which is on the way from R to S.
- What is the extra time taken by A to reach S?

Solution:
- Let the time taken by A to reach M be x hours.
- Distance covered by A = 40x km
- Distance covered by B = Distance between A and B = 60(x-2) km
- As per the problem, B overtakes A at M.
- So, distance covered by A from M to S = Distance covered by B from M to S = 400 km
- Time taken by A to cover 400 km = 400/40 = 10 hours
- Total time taken by A to reach S = Time taken to reach M + Time taken to cover 400 km = x + 10
- Distance covered by B in x hours = Distance covered by A in (x+2) hours (as they start 2 hours apart)
- So, 60x = 40(x+2)
- Solving the above equation, we get x = 4 hours
- Hence, the total time taken by A to reach S = 4 + 10 = 14 hours
- Extra time taken by A to reach S = Total time taken by A - Time taken by B to reach S
- Time taken by B to cover 800 km = 800/60 = 13.33 hours (approx)
- Extra time taken by A to reach S = 14 - 13.33 = 0.67 hours = 40 minutes

Answer:
Therefore, the extra time taken by A to reach S is 6 hours 40 minutes.
