Total distance by the object =16m+16m=32m Total time taken =4s+2s=6s Average speed=total distance travelled by total time taken = 32m by 6s =5.33ms-1 Therefore , the average speed of the object is 5.33ms-1

total distance=16 km + 16 m =16016 m total time= 4 s + 2 s =6 s average speed = total distance/total time = 16016/6 = 2669.3333....... m/s

So total average speed =1.1+8=9.1

Aayan Shahid 5 years, 10 months ago

Speed equals to distance on time Object A = 16×5/18=4.4m Average speed of objectA = Total distance travelled/ total time taken Average speed=4.4/4=1.1 metre per second Average speed of object B= Total distance travelled/ total time taken Average speed= 16/2=8 metre per second
