Answer:
<em>The bee traveled 11.7 meters.</em>
Step-by-step explanation:
A bee flew 840 cm first to land on a flower to collect some pollen and then flew another 330 cm to get back to her hive. 
For <u>finding the total distance traveled, we need to just add</u> 840 cm and 330 cm. 
So, 
We know that,  1 meter = 100 cm. That means, <u>for converting 'cm' into 'meter' , we need to divide by 100</u>. 
Thus,  
So, the bee traveled 11.7 meters.
