One method is to round 997 up to 1000, multiply by 8, and then subtract 8 times 3. This would give you the solution of 7976.

Another method (Which I personally wouldn't use) is to recursively double 997. This is more difficult, although effective. After you double 997, double the resulting number, and then double the resulting number from that, you have the solution. This is because 2^3 is 8.

If Andrew were to rest, he would not be moving (walking).  During such a period, the beginning distance would be the same as the ending distance.

In this graph there are two such time intervals:  BC and DE.  Notice how the graph is 'flat' on each; this 'flat' graph indicates a speed of zero.
