Kathy and Brian drove a total of 750 miles in 12 hours. Kathy drove the first part of the trip at 65 mph and Brian drove the res
olga2289 [7]

Answer:

<u>Kathy drove the first 9 hours of the trip and Brian drove the last 3 hours.</u>

Step-by-step explanation:

Let's review the information given to us to answer the question correctly:

Total distance of the trip = 750 miles

Time of the trip = 12 hours

Speed of Kathy = 65 mph

Speed of Brian = 55 mph

2. For what length of the time did Kathy and Brian drive?

Let's solve the problem, this way:

x = Time in hours Kathy drove

12 - x = Time in hours Brian drove

Now, let's write our equation to solve for x:

65x + 55 (12 - x) = 750

65x + 660 - 55x = 750

10x = 750 - 660

10x = 90

x = 90/10

x = 9 ⇒ 12 - x = 3

<u>Kathy drove the first 9 hours of the trip and Brian drove the last 3 hours.</u>

X-y=1 <br> X+y=3 Elimination
Mila [183]
X-y=1
x+y=3
You see the y's can cancel out. So add it together and you have:
2x=4
x=2
Now that you have x, plug it in to one of the equations to find y.
I will plug it into the first one.
(2)-y=1
-y=-1
y=1

Virty [35]

Let x represent the number of plants that they will sell in five hours

We were told that the garden store sells six plants per hour. This means that

6 plants = 1 hour

then,

x plants = 5 hours

By cross multiplying, it becomes

x * 1 = 6 * 5

x = 30

They will sell 30 plants in 5 hoursx
