Understanding the problem:
We are given that two cars, A and B, are moving in the same direction. Car A has an average speed of 40 km/h and car B has an average speed of 50 km/h. We need to find the distance between car A and car B after three hours.
Calculating the distance:
To calculate the distance between the two cars, we need to find the respective distances covered by each car in three hours.
Distance covered by car A:
The formula to calculate distance is: distance = speed × time.
Distance covered by car A = 40 km/h × 3 hours = 120 km.
Distance covered by car B:
Similarly, the distance covered by car B can be calculated as:
Distance covered by car B = 50 km/h × 3 hours = 150 km.
Calculating the difference:
To find the distance between car A and car B after three hours, we need to find the difference between the distances covered by the two cars.
Distance between car A and car B = Distance covered by car B - Distance covered by car A.
Distance between car A and car B = 150 km - 120 km = 30 km.
Conclusion:
After three hours, car B will be 30 km ahead of car A.

Distance between car A and car B = Distance covered by car B - Distance covered by car A.
Distance between car A and car B = 150 km - 120 km = 30 km.
Conclusion:
After three hours, car B will be 30 km ahead of car A.
