93.50/8.50 = 11
She can by 11 tiles.
as we know that <span>If the 4" side of the card was scaled up to 10.5
then the scaling factor is 10.5/4 = 2.625.
The 5 side would be the length 5 x 2.625 = 13.125 which exceeds the maximum dimension of 11.
Thus, it is the 5 side which is scaled up to 10.5 and the scaling factor is therefore 10.5/5 = 2.1.
The scaled up length of the 4 side is thus 4 x 2.1 = 8.4.</span>
The equation describing the situation is given by
y - 0 = (5 - 0)/(47.5 - 0) (x - 0)
y = 5/47.5 x
y = 2/19 x
Therefore, it will require 19(11)/2 = 104.5 minutes to jog 11 miles.
