Question 586202: if it takes 6hours to drive 420 kilometer, how long does it take to drive 70 kilometer?
Answer by Sudoku19(4)   (Show Source):
You can put this solution on YOUR website! Let us say that the amount of speed is the same for the rest then the solution would be:
6x = 420
x = 420 / 6
x = 70
Therefore, x = 70 is considered as 1x = 70.
So the time required it takes to drive a 70 kilometer is just 1 hour, since 1, the coefficient of x, is the amount of hours required to drive a 70 kilometer area.
More so, we could apply ratio.
6:420::x:70
The formula would be 420(x)=6(70)
This would result in 420x = 420
then x = 420 / 420
Thus producing an x (time expressed in unit hours) equal to 1.
