A bee flies at 20 feet per second directly to a flowerbed from it’s hive. The bee stays at the flowerbed for 15 minutes, then flies directly back to the hive at 12 feet per second. It is away from the hive for a total of 20 minutes. What equation can you use to fine the distance of the flowerbed from the hive?

10.5x>21+6.3x

Subtract 6.3x from both sides.

10.5x−6.3x>21

Combine 10.5x and −6.3x to get 4.2x.

4.2x>21

Divide both sides by 4.2. Since 4.2 is positive, the inequality direction remains the same.

Expand  

4.2
