Answer 1

45 / 0 time taken reaches zero and you have division by zero at

speed = 45/timeInSecs;

Answer 2

I think there is probably something wrong with startime calculation and it is actually equal to stoptime. Other thing could be the difference is actually going beyond the limit of the integer, probably use a long.
