If we start out with the formula D = R * T, we can divide both sides by R (assuming it's non zero) to get D / R = T.
So if you take the Distance from you to the Hong Kong Airport and call that D1 and the time it takes call it T1.
We get D1 / R = T1.
Assuming someone near you has a similar rateÂ, we can set up an equation for their specs and call it D2 and T2
We get D2 / R = T2.
Since the second person has already got their SCDS2, we can find out the distance and the time it took to do it, solving for R we get:
=>D2 / R = T2
=>R = D2 / T2
Now plugging in R into your equation we get:
D1 / (D2 / T2) = T1.
=>(D1 * T2) / D2 = T1
=>T1 = (D1/D2) * T2
Since D1, D2, and T2 are all given, we can approximate how many days it would take for an individual to get their Super Card DS Two
Keep in mind R is miles (kilometers) / day, D is Miles (Kilometers) / T is number of days
