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?

Mr. Smith is standing 50m from a large bell. With his mighty throwing arm, Mr.Smith throws a rock at the bell and he hears the sound of the bell 4.5s later. If the speed of sound is 330 m/s, what was the speed of the rock in the air?
