Two cars A and B are moving along a straight road in the same direction with velocities of 25km/h and 40 km /h respectively. Find velocity of car B relstive to car A?
Vb = Va + 15
Looking from the window of car A it looks like car B is going15 km/h in the + direction

To find the velocity of car B relative to car A, we need to subtract the velocity of car A from the velocity of car B.
Velocity of car B relative to car A = Velocity of car B - Velocity of car A
= 40 km/h - 25 km/h
= 15 km/h
Therefore, the velocity of car B relative to car A is 15 km/h.
To find the velocity of car B relative to car A, we need to subtract the velocity of car A from the velocity of car B. Here's how you can calculate it:
1. Understand the problem: Car B is moving faster than car A in the same direction. We want to know how much faster car B is compared to car A, in terms of velocity.
2. Identify the given information:
- Velocity of car A: 25 km/h
- Velocity of car B: 40 km/h
3. Set up the equation:
Velocity of car B relative to car A = Velocity of car B - Velocity of car A
4. Substitute the values:
Velocity of car B relative to car A = 40 km/h - 25 km/h
5. Perform the calculation:
Velocity of car B relative to car A = 15 km/h
Therefore, the velocity of car B relative to car A is 15 km/h.
