Answer 1

Answer:

5m/s is the right answer

option (b)

Answer 2

Answer:

The total distance travelled by the car= 3+3 km= 6 km that's 6000m. (As the car travels the same distance).

Total time taken for the whole journey: 10+15 min= 25 min that's 1500s.

We know, Average Speed: Total distance/ Total Time.

Therefore, 6000/1500 = 4 m/s

The correct answer is (d) 4 m/s
