To teach this, instruct that all practical percentage applications have three basic parts:
Actual amount = Rate(%) x Base (whole amount) = 1.5% x18 feet = 27/100 = .27 ft. Measurement conversion = .27 feet x12 in /1 ft = 3.24 inches
Syncrude is moving away from a dragline/conveyor belt operation to trucks and shovels, but it still has one dragline working in the north mine. Syncrude uses both metric and imperial measures onsite. A lot of their equipment comes from the US, so employees constantly have to make conversions. This is a conversion question and comes from the introductory section of the Measurement and Geometry unit of SAM.
The bucket on this unit holds 2,430 cubic feet of oil sand. It takes 55 seconds to pick up a load and dump it. How many whole cubic feet can it move per hour?
Next, determine how many cubic yards it can move per hour, round to the nearest cubic yard.
To teach this, use the following calculations:
60 x 60 = 3600 seconds per hour
3600/55 = 65.454545 dumps per hour
65.454545 x 2430 = 159,055 cubic feet per hour
159,055/27= 5891 cubic yards per hour
