3 and a half minutes = 210 seconds.

There are 3.5 times 60 = 210 minutes
3.5 minutes = 60 + 60 + 60 + 30 = 210 seconds.
There are a number of interpretations of your question: Half of 177 is 88.5 and half of 210 is 105. 88.5 + 105 = 193.5 177 + 210 = 387 387 ÷ 2 = 193.5 Half of 177 plus 210: 88.5 + 210 = 298.5
50 percent is half, or 0.5. Half of 210 or 210*0.5 = 105 ■
The half-life of the radioisotope Bismuth-210 (Bi-210) is approximately 5.01 days. This means that it takes about 5.01 days for half of a sample of Bi-210 to decay into its decay products.

Fifty percent of a number is half, so 50% (or .50) of 210 is 105.

3 and a half minutes = 210 seconds.
If you mean in 3 and a half hours then there are 210 minutes
210 minutes in 3 in half hours
With that capitalization I'm not sure, but "Po-210" is a specific isotope of polonium, a radioactive element. Po-210 has a half life of 138 days.
