There are three people needing to cross a gap of ice.
It takes three minutes for one person to cross at the highest possible speed.
The ice can support only one person at a time.
The ice will melt in eight minutes.

Spoiler for Crossing ice
How do they get across?

OP says..

I agree with puzzled. Hypothermia would set in quickly and they wouldn't make it across. (unless you count "waiting for the ice to melt" as waiting for summer).

I say the solution is they go in order of fastest to slowest and say good luck to the last person. That or fight it out and the winner runs across.
