Answer:
Given:
Cold water faucet fills the sink in 4 minutes.
Both faucets fills the sink in 3 minutes.
Let us assume that "t" be the time it takes hot water faucet in order to fill the sink.
Therefore;
<em>Rate for hot water faucet fills the sink = 
= 
</em>
<em>Rate at which cold water faucet fills the sink = = 
</em>
When both faucets are used , the rate at which they fill the sink is given as :
<em> + = 
</em>
On solving the above equation, we get :
<em>
</em>
<em>∴ 
</em>
<em>Therefore, it takes 12 minutes for the hot water faucet to fill the sink.</em>

If states instead awarded their electors on a proportional basis, it would be mathematically impossible for a candidate to lose the popular vote and still become president.
