Journey to a picnic spot:
2 friends started for a picnic spot, in two different cars. A drove his car at a constant velocity 60 km/h. B drove his car at a constant velocity 50 km/h. The velocity of B relative to A is VB – VA Similarly, the velocity of object A relative to object B is VA – VB Their friend C was supposed to wait at a point on the road for a lift. Both of them forgot to pick up C. A and B reached the picnic spot within 2 hours and 2 hours 24 minutes respectively.
What was the relative velocity of B relative to A?
- a)10 km/h
- b)– 10 km/h
- c)55 km/h
- d)– 55 km/h
Correct answer is option 'B'. Can you explain this answer?

Given information:
- A drove his car at a constant velocity of 60 km/h
- B drove his car at a constant velocity of 50 km/h
- A reached the picnic spot in 2 hours
- B reached the picnic spot in 2 hours 24 minutes
To find:
- Relative velocity of B relative to A
Calculations:
- Distance covered by A = 60 km/h x 2 hours = 120 km
- Distance covered by B = 50 km/h x (2 hours + 24 minutes/60) = 120 km
- Time taken by B to cover the same distance = 2 hours 24 minutes = 2.4 hours
- Relative velocity of B relative to A = VB - VA
- Distance covered by B relative to A = Distance covered by B - Distance covered by A = 120 km - 120 km = 0 km
- Time taken by B relative to A = Time taken by B - Time taken by A = 2.4 hours - 2 hours = 0.4 hours
- Relative velocity of B relative to A = Distance covered by B relative to A ÷ Time taken by B relative to A = 0 km ÷ 0.4 hours = 0 km/h
Answer:
- The relative velocity of B relative to A is 0 km/h
- But as B is driving slower than A, the relative velocity of A relative to B would be negative
- Therefore, the correct answer is option B) –10 km/h.
- A drove his car at a constant velocity of 60 km/h
- B drove his car at a constant velocity of 50 km/h
- A reached the picnic spot in 2 hours
- B reached the picnic spot in 2 hours 24 minutes
To find:
- Relative velocity of B relative to A
Calculations:
- Distance covered by A = 60 km/h x 2 hours = 120 km
- Distance covered by B = 50 km/h x (2 hours + 24 minutes/60) = 120 km
- Time taken by B to cover the same distance = 2 hours 24 minutes = 2.4 hours
- Relative velocity of B relative to A = VB - VA
- Distance covered by B relative to A = Distance covered by B - Distance covered by A = 120 km - 120 km = 0 km
- Time taken by B relative to A = Time taken by B - Time taken by A = 2.4 hours - 2 hours = 0.4 hours
- Relative velocity of B relative to A = Distance covered by B relative to A ÷ Time taken by B relative to A = 0 km ÷ 0.4 hours = 0 km/h
Answer:
- The relative velocity of B relative to A is 0 km/h
- But as B is driving slower than A, the relative velocity of A relative to B would be negative
- Therefore, the correct answer is option B) –10 km/h.

velocity of B relative to A = VB - VA
= 50 - 60
= -10
= 50 - 60
= -10
