The body can absorb only about 60% of the water consumed, so athletes should drink about ______ more water than what they lose through sweating.

The question seems to be missing some information. To calculate how much more water athletes should drink, we need to know the amount of water they lose through sweating. However, if we assume that the amount of water lost is X, then the calculation would be as follows:

1. Since the body can only absorb about 60% of the water consumed, this means that for every 100% of water consumed, only 60% is absorbed.
2. Therefore, to replace 100% of the water lost (X), athletes need to drink more than this.
3. To find out how much more, we divide the amount of water lost (X) by the absorption rate (60% or 0.60).

So, the formula would be X / 0.60. This will give us the total amount of water athletes should drink to replace what they lose through sweating.
