Question

an object travels 16 km in 4 sec and another 16 km in another 4 sec what is the average speed

Answer 1

Answer:

4 km/s

Explanation:

Total distance = 16 km + 16 km = 32 km

Total time = 4 sec + 4 sec = 8 seconds.

⇒     Average speed = (Total distance/Total time)

                        v = 32/8 km/sec = 4 km/sec
