Answer:
Below in bold.
Step-by-step explanation:
a. Distance = speed * time
d = st
So substituting in the given values:
d = 9t where t is the time it takes to travel from the hive to the flowerbed.
The total time that the bee is inflight = 19 - 16 = 3 minutes
= 180 seconds.
So for the return flight the time taken is (180-t) seconds.
So d = 6(180 - t).
and we can find the distance from the hive to flowerbed by solving the the 2 equations highlighted.
b, d = 9t
d = 6(180 - t).
Therefore:
9t = 6(180 - t)
9t = 1080 - 6t
9t + 6t = 1080
15t = 1080
t = 72 seconds
So Distance d = 9*72
= 648 ft.
c. d = 9t.
