Answer:
Below in bold.
Explanation:
a. Distance = speed * time
d = st
So substituting in the given values:
d = 20t where t is the time it takes to travel from the hive to the flowerbed.
The total time that the bee is inflight = 13-11 = 2 minutes
= 120 seconds.
So for the return flight the time taken is (120-t) seconds.
So d = 16(120 - t).
and we can find the distance from the hive to flowerbed by solving the the 2 equations highlighted.
b, d = 20t
d = 16(120 - t).
As both right side expressions are equal to d we can write:
20t = 16(120 - t)
20t = 1920 - 16t
20t+ 16t = 1920
t = 1920/36
= 53.33 seconds.
So the distance from hive to flowerbed
= 53.33 * 20
= 1066.67 feet.
