Marta's house is 3.10 miles from Latanya's house
What is speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.
Given that Latanya leaves her house at 12:30 p.M. She bikes at 12 mi/hr to Marta's house She stays at Marta's house for 90 minutes Both girls walk back to Latanya's house at 2.5 mi/h They arrive at Latanya's house at 3:30 p.M.
We need to know how far is Marta's house from Latanya's house
∵ Latanya starts her trip at 12:30 p.M.
∵ She returns home at 3:30 p.M.
∴ The time of her trip is → 3:30 - 12:30 = 3 hours
- But she stays at Marta's house for 90 minutes
∵ 1 hour = 60 minutes
∴ 90 minutes = 90 ÷ 60 = 1.5 hours
∴ The time from her house to Marta's house and from Marta's house to her house is → 3 - 1.5 = 1.5 hours
Assume that the distance from her house to Marta's house is d and the time from her house to Marta's house is t₁ and the time from Marta's house to her house is t₂
∵ Latanya bikes at 12 mi/h to Marta's house
∵ Distance = speed × time
∴ d = 12 × t₁
∵ Both girls walk back to Latanya's house at 2.5 mi/h
∴ d = 2.5 × t₂
Equate the two expressions of d
∴ 12 = 2.5 ⇒ (1)
∵ t₁ + t₂ = 1.5
Subtract from both sides
∴ t₂ = 1.5 - t₁ ⇒ (2)
Substitute equation (2) in equation (1)
∴ 12t₁ = 2.5(1.5 - t₂ )
∴ 12 = 3.75 - 2.5
Add 2.5 t₁ to both sides
∴ 14.5t₁ = 3.75
Divide both sides by 14.5
t₁ = 15 / 38 hour
∴ She spends 15/58 hours biking Marta's house. Let's find d
∵ d = 12t₁
∴ d = 12 x ( 15 / 38 ) miles
Therefore, Marta's house is 3.10 miles from Latanya's house

The first side of a triangle is 7 cm shorter than twice the second side. The third side is 4 cm longer than the first side. The perimeter is 90 cm. Find the length of all three sides.
Please answer! Im giving half of all my points!!
Answer:
first side = 33
second side = 20
third side = 37
Step-by-step explanation:
first side = 2x-7
second side = x
third side = (2x-7)+4
(2x - 7) + x + (2x - 7) + 4 = 90
5x - 14 + 4 = 90
5x - 10 = 90
+10 +10
5x = 100
x = 20
first side:
2(20)-7
40 - 7 = 33
second side: 20
third side:
(2(20) - 7) + 4
(40 - 7) + 4
33 + 4 = 37
A community group is picking up trash along a portion of the highway that is 1.48 miles long. In one hour they can clean a section about 1/8 mile long. Approximately how many hours will it take the group to clean the stretch of highway?
Please help ASAP
The answers are
3/16
16/3
2
12
Answer:
12 if im correct
Step-by-step explanation:
first we have to see that they are doing 1/8 of a mile per hour so if we divide 1.48 by 1/8 it should give us the time
first we convert 1/8 to a decimal which is .125 and we divide 1.48 by .125
giving us 11.84
since it is time, 11 hrs would be too little of a time so we need to round up to 12
Hope thats right
The number of hours for the group to clean the stretch of highway is A = 12 hours
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
In an equation, the expressions on either side of the equals sign are called the left-hand side (LHS) and the right-hand side (RHS), respectively. The equals sign (=) indicates that the two expressions have the same value, and that the equation is true for certain values of the variables involved.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. It typically consists mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation.
Given data ,
Let the number of hours be represented as A
Now , the value of A is
If the group can clean 1/8 mile of the highway in one hour, we can calculate how many sections of 1/8 mile are in 1.48 miles:
1.48 miles / (1/8 mile per section) = 11.84 sections
On simplifying the equation , we get
This means that the group will need to clean 11.84 sections of 1/8 mile each to clean the entire stretch of highway.
Since they can clean 1 section in 1 hour, it will take them 11.84 hours to clean the entire stretch of highway ≈ 12 hours
Hence , the number of hours to clean the highway is 12 hours
