a lamp post has half of its length in mud,1 by 3 of its length in water and 3 whole 1by3m above water. find the whole length of the post
Answer: 20mStep-by-step explanation: Correct option is A)Let the total length of the post be x mThen length of post in mud= x/2Length of post in water = x/3Givenx/2-x/3=10/3x/6=10/3x=20
Answer:20 mStep-by-step explanation:Given:
Let x be the length of the lamp post.Convert 3 ¹/₃ to an improper fraction:The total length of the lamp post (x) is the sum of the three given lengths:Multiply both sides by 6:Isolate x:Therefore, the whole length of the post is 20 m.
- Length in mud = ¹/₂ its length
- Length in water = ¹/₃ its length
- Length above water = 3 ¹/₃ m
