Yes, Jackie qualified for the competition.

Step-by-step explanation:

The necessary jump in 3 combine jumps = More than 16 m

Now, distance covered by Jackie in first jump =  4.86 m

Distance covered by Jackie in second jump =  5.428 m

Distance covered by Jackie in third jump = 5.9 m

So, the sum of total distance covered by Jackie in 3 jumps  

= Distance covered is  (first + second  +  third ) jump

= 4.86 m + 5.428 m + 5.9 m   =  16.188 m

⇒ In 3 attempts, Jackie covers a total distance of  16.188 m

and  16.188 m  >  The qualifying mark of 16 m

Hence,  Yes, Jackie qualified for the competition.
