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.
Answer:
i got x=-135
Step-by-step explanation:
lets solve!
first remove the parentheses= x-1.2x=27
second you collect like terms= -0.2x=27
last divide both sides by -.02 = x=-135
hope this helps you!! :)
Answer:
4/7
Step-by-step explanation:
Distance remaining at the end of Saturday's trip = 1 - 2/7
= 7/7 - 2/7 = 5/7
Fraction travelled on Sunday = 5/7 x 4/5 = 4/7
