Points A and B are 150 km apart. Cars 1 and 2 travel from A to B, but car 2 starts from A when car 1 is already 20 km away from A. Each car travels at a speed of 100 kmph for the first 50 km, at 50 kmph for the next 50 km, and at 25 kmph for the last 50 km. The distance, in km, between car 2 and B when car 1 reaches B is
Correct answer is '5'. Can you explain this answer?

Points A and B are 150 km apart. Cars 1 and 2 travel from A to B, but...
Time taken to cover first 50 km at 100 km/hr = 1/2 hr.

Time taken to cover second 50 km at 50 km/hr = 1 hr.
Time taken to cover last 50 km at 25 km/hr = 2 hr.
When car 2 starts, car 1 has already covered 20 km.
So, time taken by car 1 to reach B after car 1 starts = total time - time required to travel first 20 km
= 3 hr 30 min -12 min = 3 hr 18 min
Distance travelled by car 2 = (50 + 50 + 45) = 145 km
Distance from B = (150 -145) km = 5 km
Hence, 5 is the correct answer.

Finding the time it takes for car 1 to reach point B:
To find the time it takes for car 1 to reach point B, we need to calculate the total time it takes for car 1 to travel the entire distance between points A and B.
- Distance traveled at 100 kmph: 50 km
- Distance traveled at 50 kmph: 50 km
- Distance traveled at 25 kmph: 50 km
The time taken to travel each distance can be calculated using the formula: time = distance / speed. Thus,
- Time taken to travel 50 km at 100 kmph: 50 / 100 = 0.5 hours
- Time taken to travel 50 km at 50 kmph: 50 / 50 = 1 hour
- Time taken to travel 50 km at 25 kmph: 50 / 25 = 2 hours
The total time taken for car 1 to reach point B is 0.5 + 1 + 2 = 3.5 hours.
Finding the distance between car 2 and B when car 1 reaches B:
Car 2 starts from point A when car 1 is already 20 km away from A. Therefore, car 2 has to travel a total distance of 150 - 20 = 130 km to reach point B.
Since both cars travel at the same speeds, the time taken for car 2 to reach point B is also 3.5 hours.
To find the distance between car 2 and B when car 1 reaches B, we need to subtract the distance traveled by car 2 in 3.5 hours from the total distance between A and B.
- Distance traveled by car 2 in 3.5 hours:
- Distance traveled at 100 kmph: 50 * 100 = 5000 km
- Distance traveled at 50 kmph: 50 * 50 = 2500 km
- Distance traveled at 25 kmph: 30 * 25 = 750 km
The total distance traveled by car 2 is 5000 + 2500 + 750 = 8250 km.
The distance between car 2 and B when car 1 reaches B is the difference between the total distance between A and B and the distance traveled by car 2 in 3.5 hours:
150 - 8250 = -8100 km
Since the distance cannot be negative, we take the absolute value:
| -8100 | = 8100 km
Therefore, the distance between car 2 and B when car 1 reaches B is 8100 km.
However, the given correct answer is 5 km. It seems like there might be an error in the calculations or the given data. Please double-check the information and calculations to ensure accuracy.
