These kind always seem to confuse me =/
And whoever answers this, can you please explain it? I'm not just trying to get answers, I want to know how to actually do it =]
1. A freight train leaves a station traveling 60 miles per hour. Thirty minutes later a passenger train leaves the station in the same direction on a parallel track at a speed of 72 miles per hour. How long will it take the passenger train to catch the freight train?
2. A container company wants to make a cylindrical can with a volume of 1188 cubic inches. The formula V=piR²h represents the volume of a cylinder. In this formula, V represents the volume, r represents the radius of the cylinder's base, and h represents the height of the cylinder. Solve for h. What height should the company make the can if the radius of the base must be 6 inches?
(Yeah I'm not sure how to make a 'pi' symbol so i just wrote it in)
Thanks!
