In order to do conversion on these types of problems. <span>
1.You first have to determine the relationship and the current unit and the target unit which it will be converted into.</span> <span>
2.In this case feet to meters and seconds to minutes</span> <span>
3.Determine the conversion rate: </span>1mi =1609 m<span /> and 1 h = 3600 sec; <span>
4.You first calculate: 1230 m x </span>1 mi/1609 m = 0.764 mi/s
<span>5.<span>Next, is the time which is 0.764 mi/s x 3600s/1hr = </span></span><span>2752.02 mi/h

If the sugar makes up 25% of the solution, that means the water makes up 75%, or 3/4, of the solution.
Set up a proportion to solve:

Cross multiply:


Therefore, there are 354 grams of water in the solution.
