Answer:
a. 15 = d/600 + 12 + d/480
b. 800 feet
Step-by-step explanation:
a. Let distance between hive and flowerbed be "d" feet
Speed of bee during motion from hire to flowerbed = 10ft / sec = (10*60)fit/minute
Speed of bee during reverse motion = 8 ft/sec = (8*60)ft/min
Time which the bee stayed at flower bed = 12 minute
Time of its total journey = 15 minutes
Total Time = Time of travel from hive to flowerbed + Time of staying in flowerbed + Time of reverse travel
15 = d/10*60 + 12 + d/8*60
15 = d/600 + 12 + d/480....................(Required equation)
b. 15 = d/600 + 12 + d/480
d/600 + d/480 = 15 - 12
d/600 + d/480 = 3
<u>4d + 5d </u> = 3
2400
9d = 2400 * 3
9d = 7200
d = 7200/9
d = 800 feet
Hence, the flowerbed is 800 feet far from the hive.
Isolate the variable by dividing each side by factors that don't contain the variable.

Decimal Form:
x=206.14251569…x=206.14251569…
Subtract 3x from 5x getting 2x so your new equation is: 2x-1/4=-5/4 then you add 1/4 to -5/4 getting : 2x=-1 the you divide both sides by 2 so x=-1/2<span>
