A straight road connects points A and B. Car 1 travels from A to B and...
Given Information:
- Car 1 travels from point A to point B at a speed of 60 km/hr.
- Car 2 travels from point B to point A.
- Both cars leave at the same time.
- Car 1 takes 45 minutes to complete its journey after meeting Car 2.
- Car 2 takes 20 minutes to complete its journey after meeting Car 1.

Understanding the Scenario:
- When Car 1 and Car 2 meet, they have traveled the same distance.
- Let the distance between points A and B be D km.
- Let the speed of Car 2 be x km/hr.

Calculating the Time taken by Car 1 and Car 2:
- Car 1 takes 45 minutes (0.75 hours) to cover the remaining distance D at a speed of 60 km/hr.
- Car 2 takes 20 minutes (0.33 hours) to cover the remaining distance D at a speed of x km/hr.

Using the formula:
Time = Distance/Speed
- For Car 1: 0.75 = D / 60
- For Car 2: 0.33 = D / x

Finding the speed of Car 2:
- From the above equations, we can find the value of D.
- D = 60 * 0.75 = 45 km
- Substituting the value of D in the second equation:
0.33 = 45 / x
x = 45 / 0.33
x ≈ 136.36 km/hr

Conclusion:
- The speed of Car 2 is approximately 136.36 km/hr, which is not in the given options.
- However, this calculation is incorrect, and the correct answer is option 'A' (90 km/hr).
- There might be a mistake in the calculation or assumptions made, leading to the incorrect answer.

In this particular case, we know Ratio of speeds = 
C1 : C2 = √20 : 45 i.e., 2: 3
As the speed of Car C1 is 60 kmph, the speed of Car C2 is 90 kmph

Five students - K, L, M, N and O travel from Mumbai to Delhi which are 100 km apart. All students change their mode of transport immediately after completing first 50 km. Mumbai to Delhi can be travelled by train, bus, ship, plane or monorail. Each student uses different mode of transport for the first half of the journey and the same is true for the remaining part of the journey. The time required ( in integers only) for a particular mode is same in both the halves.The table gives the total time taken by each student.Also the following information is given :1. Had anyone used bus and monorail for his travel then he would have taken 9 hrs to complete his journey.2. M uses both plane and ship for his travel.3. Plane is the fastest and monorail the slowest.Q.If N travels first 50 km by ship, what mode of transport does M use for the first 50 km?
