Stu hiked a trail at an average rate of 3 miles per hour. He ran back on the same trail at an average rate of 5 miles per hour. He traveled for a total of 3 hours. The equation 3t = 5(3 – t) can be used to find the time it took Stu to hike one way. How long did it take Stu to hike the trail one way? hours How long is the trail? miles What is the total distance Stu travelled? miles
Answers
Answer:
Time taken to travel at 3 miles = 1.875
Time taken to travel at 5miles = 1.125
Total distance = 11.25
Step-by-step explanation:
D = speed x time
Time = distance/speed
Time at 3 miles per hour and 5 miles per hour
T1 = d/3
T2 = d/5
Total time = 3 hours
T1+t2 = 3 hours
d/3 + d/5 = 3
= d(1/2+1/5) = 3
d(5+3/15) = 3
d(8/15) = 3
We cross multiply
8d = 45
d = 45/8
= 5.625 miles
Total distance = 2d
2x5.625 = 11.25 miles
Since d is now known
T1 = 5.625/3 = 1.875 hours also 1 hour 52.5 minutes
T2 = 5.625/5 = 1.125 hours = 1 hour 7.5 minutes
Total distance 2xd = 11.25
Answer:
the answer is
A. 1.875 hours
C. 5.625 miles
D. 11.25 miles

An ice cream shop charges customers a set amount for one scoop of ice cream, plus a charge per topping. If two toppings would cost a total of $3.99, and 4 toppings $4.99, what is the rate per topping?
Answers
Answer:
$0.50 per topping
Step-by-step explanation:
x + 2t = 3.99
x + 4t = 4.99
x + 2t = 3.99
2t = 3.99 - x
t = 1.995 - 0.5x
x + 4t = 4.99
x + 4(1.995 - 0.5x) = 4.99
x + 7.98 - 2x = 4.99
7.98 - x = 4.99
-x = -2.99
x = 2.99
t = 1.995 - 0.5(2.99)
t = 1.995 - 1.495
t = 0.50
The rate per toppings is given by the equation A = $ 0.50
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of the toppings be represented as A
Now , the equation will be
The cost of 2 toppings = $ 3.99
So , 2A = 3.99 be equation (1)
The cost of 4 toppings = $ 4.99
And , 4A = 4.99 be equation (2)
Subtracting equation (1) from equation (2) , we get
4A - 2A = 4.99 - 3.99
On simplifying the equation , we get
2A = 1.00
Divide by 2 on both sides of the equation , we get
A = $ 0.50
Therefore , the value of A is $ 0.50
Hence , the cost of one toppings is $ 0.50
