Answer the following problems showing all work. Showing all work means using the steps stated in Dimensional Analysis Notes and math rules.

Conversion factors 1 in = 2.54 cm

1. Remy that curious cat can run 31.2km/hr. How fast can he go in ft/sec?








2. If Remy wanted to run 4.5E3m, how long (in days) will it take him? Assume he run at same speed as above problem.









3. Duxbury football team can eat 1.5 hamburgers/(player-hr). How many burgers will the team eat if there are 11 players and they eat for 2.5 hrs?







4. The density of the hamburger that the Duxbury football team eat has D = 1.24g/cm3. Assume each hamburger was 210.g, what is the volume of the hamburger. (We are assuming the hamburger is one substance.)







Answer: 1) 28.4ft/sec , 2) 6.0E-3 days , 3) 41 hamburgers
4) 169cm3 for 1 hamburger, if assumed 41 hamburgers (from Q3) then 6.94E3 cm3 or 6.94 L
