Answer

Christian Sandstrom's throw was 250 meters.

Work Step by Step

We know that Valerie's throw was 148 meters and that Christian's throw was 68.9% farther than hers. This is mathematically represented by the equation $\frac{x - 148}{148}$ = 0.689, where x is the length of Christian's throw in meters. To solve for x, simply multiply 148 $\times$ 0.689, and then add 148 to get 249.972. The problem says to round to the nearest meter, so our answer is 250 meters.
