For a road trip a car of travelers can take the direct route or the scenic route. The scenic route takes 25% longer than the dir

MariettaO [177]

Answer:

the scenic route take 6h 40m

Step-by-step explanation:

first we have to make an equation that represents the relationship of each route

x = scenic route

y = direct route

x = y + y * 25/100

now we have to make an equation that represents the routes over time

x + y = 12

we replace the x by what is the same in the first equation (y + y * 25/100) in the second equation

x + y = 12

(y + y * 25/100) + y = 12

2 y + 0.25 y = 12

2.25y = 12

y = 12/2.25

if we spend this in minutes multiplying it by 60

y = 12/2.25 * 60 = 320 m = 5h 20m

x + y = 12

x + (5h 20m) = 12h

x = 12h - 5h 20m

x = 6h 40m

It takes Sue, Jeff and Todd 4 hours to paint a room together. If it takes Sue 10 hours by herself and Jeff 12 hours by himself,

diamong [38]

The number of time it would take Todd to paint the room alone is 15 hours.

Let the Todd's time be t.

Given the following data:

Combine time = 4 hours

Sue's time = 10 hours

Jeff's time = 12 hours

To calculate the number of time it would take Todd to paint the room alone:

How to solve a word problem:

In order to solve this exercise, we would first of all calculate their individual rate and combined rate respectively. Finally, we would add their individual rates together and equate it to the combined rate.

For Sue:

$Rate = \frac{1}{10} \;work/hr$

For Jeff:

$Rate = \frac{1}{12} \;work/hr$

For Todd:

$Rate = \frac{1}{t} \;work/hr$

Combined rate:

$Rate = \frac{1}{4} \;work/hr$

Adding the individual rates, we have:

$\frac{1}{10} +\frac{1}{12} +\frac{1}{t} =\frac{1}{4} \\
\\
$

Multiplying all through by 120t, we have:

$12t+10t+120=30t\\
\\
22t+120=30t\\
\\
120=30t-22t\\
\\
120=8t\\
\\
t=\frac{120}{8}$

t = 15 hours.
