Mo2men wrote:At what speed was Erik running when he was at the halfway point of his route?
1. Erik's route was 10 miles long and took him 2 hours to complete.
2. Erik ran at an average speed of 5 miles per hour on the route
Statements combined:
Each statement conveys the same information: that the average speed for the whole trip was 5 miles per hour.

At the halfway point, the speed could be ANY NONNEGATIVE VALUE.
Thus, the two statements combined are INSUFFICIENT.
The correct answer is
