He starts at a speed of 4 fps.
He adds 2 fps of speed during each of 3 seconds, for a gain of 6 fps.
At the end of the 3 sec, his speed is (4 + 6) = 10 fps.
We know nothing about the direction in which he runs, so we're in no position to discuss velocity. The best we can do is to determine his final speed.

Given :
An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 g of an alloy containing 12% copper with 78 g of an alloy containing 92% copper.
To Find :
How many grams of copper are in the resulting mixture what percentage of the resulting mixture is copper.
Solution :
Mass of copper in 50 gm alloy =
.
Mass of copper in 78 gm alloy =
.
Total mass of copper, ( 6 + 76.44 ) gm = 82.44 gram.
Percentage of copper in resulting mixture :

Hence, this is the required solution.

If, for example, the usual price of the cycle is $4,100, and we want to know how much one could save by buying the cycle at $3,600, we must subtract $3,600 from $4,100:
$4,100
- 3,600
-----------
$500
