An object travels 20m in 4sec and then another 16m in 2sec .What is the average speed of an object ?
Answers
Answer:
average speed = total distance / total time
total distance = 20 + 16 = 36 m
total time = 4 + 2 = 6
so average speed = 36/6 = 6 m/s
so the average speed of the object is 6 m/s

Answer:
4.5m/second
Explanation:
Distance 1 = 20 m
Time 1 = 4 s
Distance 2 = 16m
Time 2 = 2 s
Total distance(D) = 20m + 16m= 36m
Total Time(T) = 4s + 2s = 8s
*We know the formula of speed is S= D/T ( Speed = Distance/Time)
S= 36/8
S= 4.5m/second
Hence, the average speed of the object is 4.5m/second.
