1)What is the rate of speed in miles per hour a marble will attain after falling through an inclined tube?

with an incline using a book, a board, a couch cushion, etc. Measure the incline in feet or inches. Using your phone or another device, time how long (in seconds) it takes for a marble to roll down an incline. Represent the rate in terms of feet per second. Then convert to miles per hour (mph).

 

There are 5,280 feet in a mile and 3,600 seconds in an hour. .

 

2)How long in minutes will it take for a 500-gallon reservoir tank to be emptied by your kitchen sink?

Find the rate at which the sink releases water in gallons per minute. Time how long it takes to fill a gallon container (a milk or water jug, for example). This will give you a rate of gallons per minute. Use this to calculate minutes.

 

3)How long in hours would it take to walk from campus to Ogdensburg? The distance from campus to Ogdensburg is 19.5 miles.

Find a human walking rate, by walking in the hallway and timing how long it takes (seconds) to walk a measured distance (feet). Your rate will be feet per second. Convert to miles per hour, and calculate time it will take to walk to Ogdensburg.

 

 

 4)Provided with sand, determine if one could fill a 15 cubic yard dump truck box with sand and not exceed the weight limit of 40 tons.

Given: Density = Mass/Volume. The density of sand is 2.9 g/ml.

1 Kg = 1000 g.                    1 yard³ = 27 feet³

1 Ton = 1,000 Kg.               1 foot³ = 28.32 Liters

 

5)Determine the amount of water used by four individuals each filling a bath for 10 minutes every day for a year.

Determine the number of gallons per minute that dispenses using only the cold water faucet as the water source.
