Practice Question 2
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.
Answer:
To teach this, use the following calculations:
¾ Number of seconds per hour
¾ 1 cubic foot = 1/27 cubic yard
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
