Answer:

The bee travelled a total distance of 11.7 metres, in order to collect pollen from a flower and then back to its hive.

Note: The question is not clearly stated. A similar but clearly stated question is given below:

A bee flew 840 cm and landed on a flower to collect some pollen. Then the bee flew another 330 cm to get back to her hive. How many meters did the bee travel?

Explanation:

Th distance travelled by the bee is the sum total of all the ground covered by the bee.

The initial distance travelled by the bee to get to the flower = 840 cm

After collecting pollen from the flower, the distance travelled by the bee to get to its hive = 330 cm

The total distance travelled by the bee = 840 cm + 330 cm = 1170 cm

The distance covered in centimetres is then covered to metres

100 centimetres = 1 metre

Therefore, 1170 cm = 1170 cm × 1 m /100 cm = 11.7 m

Therefore, the bee travelled a total distance of 11.7 metres, in order to collect pollen from a flower and then back to its hive.
