P and Q starting simultaneously from two different places proceed towards each other at a speed of 20 km/hour and 30 km/hour respectively. By the time they meet each other, Q has covered 36 km more than P. The distance (in k.m.) between the two places is:
  • a)
    108
  • b)
    144
  • c)
    162
  • d)
    180
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
P and Q starting simultaneously from two different places proceed tow...
Let the distance = x km
Let they meet when P travels y km.
then, Q travels in the same time x – y km
from question,
(x – y) – y = 36
x – 2y = 36 .......(i)
Also, 20 × y = 30 (x–y) [∵Time is same]
∴y/x−y−=3/2
2y = 3x – 3y
5y = 3x ........(ii)
Putting the value of y from (ii) to (i),
x−6x/5=36⇒−x/5=36⇒x=180 km

P and Q starting simultaneously from two different places proceed tow...

Approach:
Let the distance between the two places be x km.
The time taken for P and Q to meet each other is the same.
We can use the formula:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]

Calculating the time taken:
Let the time taken be t hours.
For P, the distance covered will be 20t km.
For Q, the distance covered will be 30t km.

Calculating the difference in distance:
According to the given information, Q has covered 36 km more than P.
Therefore, 30t - 20t = 36
Solving for t, we get t = 4 hours.

Calculating the distance between the two places:
Substitute the value of t back into the distance formula:
Distance covered by P = 20 km/hr x 4 hr = 80 km
Distance covered by Q = 30 km/hr x 4 hr = 120 km

The total distance between the two places = 80 km + 120 km = 200 km

Therefore, the correct answer is option D) 180 km.
