Answer:
A
Step-by-step explanation:
What we need to know simply is the time taken for both trips. We know the car spent 6 hours on the first leg, that is settled.
What we do not know is the time spent on the second leg. To get the time spent on the second leg of the journey, we only need to get the total distance divided by the speed.
We can get the distance using the first part of the question. The time is 6 hours and the speed is x miles per hour, the total distance is this 6x miles.
Now we need to know the time spent on the second leg of the journey. We know that the distance is the same. Hence the time spent is 6x/y where y is the speed for the second leg and 6x is the length of each leg
Now the total time spent is thus (6x/y +6) hours. We need to however convert this to minutes. We do this by multiplying by 60
(6x/y + 6) * 60
Lateral area is the area of the faces, while surface area is the area of the faces and and bases.
Answer:
x=1
Step-by-step explanation:
you would substitute the first equation in for the y in the second equation
x + 2x+3 =6
then you would combine the x's
3x +3 = 6
Then you would move the 3 to the other side with the six
3x =6-3 3x = 3
Then finally you would divide the three
3x/3 = 3/3 x=1
