One of the radiator hoses blew a hole. Can duct tape fix until I get new hose?

I've used duct tape on my shoes, but it's not good for radiator hoses. Mechanics are masters at nursing wounded cars long distances but only to get them home or to the shop. We don't put our faith in these cobble-jobs, and they are just to delay the inevitable. The ONLY acceptable fix is a new hose. The question is how much trust can you put in the repair before you have to fix it right?

That said, I blew a heater hose on my '72 Challenger a few years ago a long way from home or my buddy's repair shop. I used electrical tape to seal the split that was about two inches long, then, since electrical tape unravels into a gooey mess when it gets hot, I put two hose clamps over it once I got to my friend's shop. I also left the radiator cap loose by one click so no pressure could build up in the system. That makeshift repair lasted way too long before I replaced all the hoses. When one splits it's because it rotted from the inside where you can't see it. All the other hoses are in the same condition waiting to fail the same way.
