Jack the Jaguar can run for only 1.0 min at 13.0m/s before he has to stop to rest, while Zeke the zebra can gallop at 7.25m/s for 5.0 min. How long does Zeke actually have to run for to elude Jack? Can Jack catch Zeke for lunch if they are initially 350m apart?

The first question makes little sense, but the second can be answered by solving
13s = 7.25s+350
s = 60.87
Since Jack has to stop after only 60 seconds, he'll watch Zeke's heels as he escapes. One more second and he'd have had zebra for lunch.
