180/3 = 60
Therefore the car traveled 60km per hour.
7/12 14/24 21/36 28/48 35/60

1² - (1.5x⁴)² =
(1 + 1.5x⁴)(1 - 1.5x⁴)
When surface area is minimized, that means the less material companies would have to use for the can. Companies can spend less money on aluminum for the can and still hold the same amount of that beverage inside the can.
A direct variation suggest that the value of x in the equation would greatly affect the value of y such that when x is increasing, y also increases and the other way around. The equation for a direct variation is that,
y = kx
Substituting the given values in the ordered pair,
5 = k(4) ; k = 5/4
